IIS 8.0 Hosting UK - HostForLIFE.eu :: Publishing React on IIS

clock May 8, 2024 08:29 by author Peter

There are a few tricks involved in deploying React on Internet Information Service.

Installing the rewrite module on Windows, configuring the IIS pool, selecting the port to run your React project on, copying the web.config, and setting up your project in an Index.html file are all necessary.

The steps to help you are as follows.
Now let's get going.

These two scripts should be added to the end of the body of your React project's Index.html in the public folder.

<script src="https://unpkg.com/react@18/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@18/umd/react-dom.development.js" crossorigin></script>

When the code is published for production, please alter the .development.js to .production.min.js.
On your project, run the build command.
npm run build

Copy the files from the build folder to your IIS target folder.
Add this web. config in the target folder under IIS.
<?xml version="1.0" encoding="UTF-8"?>
               <rule name="Static Assets" stopProcessing="true">
                    <match url="([\S]+[.](html|htm|svg|js|css|png|gif|jpg|jpeg))" />
                    <action type="Rewrite" url="/{R:1}"/>
                <rule name="ReactRouter Routes" stopProcessing="true">
                    <match url=".*" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    <action type="Rewrite" url="/index.html" />

To make it work, you must install a rewrite module if you haven't it.
https://www.iis.net/downloads/microsoft/url-rewrite, choose your language, download, and install it.
Adjust the pool

Adjust your binds and default port.
Choose Bindings, and click on Edit.
Choose a Port for your React app to work.

Now, you must have your first React app on IIS working. Good lucky!

IIS 8.0 Hosting UK - HostForLIFE.eu :: Error Message 401.2: Unauthorized - Logon Failed Due To Server Configuration

clock March 7, 2024 06:40 by author Peter

Sometimes we receive this error message after publishing the solution in IIS. This mistake is very common.

Exact Error
Error message 401.2: Unauthorized The login failed due to server configuration. Check that you have authorization to browse this directory or page using the credentials you provided and the authentication methods enabled on the Web server. For further assistance, contact the web server administrator.

This problem is mostly caused by IIS's authentication settings.

Launch the IIS.

Choose the site where you are experiencing the problem.
Select Authentication. Setting as indicated.

Authentication choices can be updated based on your application's requirements.

In my case, the application needs to set windows authentication, therefore, I set it to enabled and Anonymous Authentication Disabled.

IIS 8.0 Hosting UK - HostForLIFE.eu :: Protect Static Files In ASP.NET Web Forms With The Help Of HTTP Handle

clock February 27, 2024 08:03 by author Peter

First, let me explain the problem I encountered in the web forms application (ASPX). I have a legacy web application that was created in ASP.NET and deployed on IIS 10. Static files (PDF, JS, CSS, JSON, and all forms of pictures (jpg, png, BMP, etc.)) are stored in a subfolder on the site called data, such as http://example.com/data/...When an unauthenticated person browses the files.


http://example.com/data/image.gif or http://example.com/data/sample.css or http://example.com/data/sample.js).
It will display the files without authentication. In other words, the pages should only be accessible once the user is authorized.

IIS Default Behavior By default, the IIS web server routes ASP.NET resource requests to the ASP.NET runtime, but it handles static content requests directly. As a result, requests for static content are served without consideration for the URL authorization requirements specified in the ASP.NET application settings.

When I try to browse this issues regarding the same in internet , there are lot of things like enabling runAllManagedModulesForAllRequests="true" but nothings works out. Even though I am running my application in integrated mode in IIS.

Then I came to know about HTTPHandler. Below is the definition of HTTP Handler from Microsoft.

HTTP modules and HTTP handlers are an integral part of the ASP.NET architecture. While a request is being processed, each request is processed by multiple HTTP modules (for example, the authentication module and the session module) and is then processed by a single HTTP handler. After the handler has processed the request, the request flows back through the HTTP modules.

HTTPHandlers are used by ASP.NET web application server to handle specific requests based on extensions. HTTPHandlers run as processes in response to a request made to the ASP.NET website. It is a class that implements the System.
How to implement HTTPHandler to handle any incoming HTTP request with a path like .gif/.js/.css?

  • Create a class file — it could be FileProtectionHandler.cs
  • Let FileProtectionHandler class inherit from IhttpHandler Interface.
  • In FileProtectionHandler class, implement all the methods which are found in IhttpHandler Interface.

When a request comes, it will check whether it will be authenticated or not, if not it will redirect to login page otherwise will send the requested file based on the file extension.
using System;
using System.IO;
using System.Web;
namespace Example.UI {
    public class FileProtectionHandler: IHttpHandler {
        /// <summary>
        /// You will need to configure this handler in the Web.config file of your
        /// web and register it with IIS before being able to use it. For more information
        /// see the following link: https://go.microsoft.com/?linkid=8101007
        /// </summary>
        #region IHttpHandler Members
        public bool IsReusable {
            // Return false in case your Managed Handler cannot be reused for another request.
            // Usually this would be false in case you have some state information preserved per request.
            get {
                return true;
        public void ProcessRequest(HttpContext context) {
            //write your handler implementation here.
            if (!context.User.Identity.IsAuthenticated) {
            } else {
                string requestedFile = context.Server.MapPath(context.Request.FilePath);
                SendContentTypeAndFile(context, requestedFile);
        private HttpContext SendContentTypeAndFile(HttpContext context, string strFile) {
            context.Response.ContentType = GetContentType(strFile);
            return context;
        private string GetContentType(string fileName) {
            string res = null;
            FileInfo fileInfo = new FileInfo(fileName);
            if (fileInfo.Exists) {
                switch (fileInfo.Extension.Remove(0, 1).ToLower()) {
                    case "pdf": {
                        res = "application/pdf";
                    case "gif": {
                        res = "image/gif";
            return res;

The next step is to register the HTTP handler in the Web.config file. Based on your IIS version, it should be added as a child of <system.web> or <system.webServer>. Refer here to register
    <add path="*.gif" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.png" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.jpg" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.js" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.svg" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.bmp" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.json" verb="*" type="MyProject.FileProtectionHandler" validate="false" />
    <add path="*.css" verb="*" type="MyProject.FileProtectionHandler" validate="false" />

That’s all. Now HTTP Handler is ready
Once this configuration information has been specified in Web.config revisit the image file hosted via IIS from your browser. This time while processing the request for the image file IIS allows for the ASP.NET runtime to perform authentication and authorization logic. The ASP.NET runtime notes that the request is coming from an anonymous user and is for a URL that denies anonymous users. Therefore, the anonymous user is redirected to the login page, just like when visiting the image file served by the ASP.NET Development Server.

IIS 8.0 Hosting UK - HostForLIFE.eu :: Recognizing and Handling.Net Server-Side (Output) Caching

clock January 29, 2024 07:41 by author Peter

A user's request does not go to the database every time they visit a website in order to answer every detail. As an alternative, some data is extracted directly, which speeds up and improves efficiency. This tactic enables the server to process numerous requests from various users without interfering with the database. Important information is stored in the server's memory so that it can respond to your request promptly.

Given that data is typically saved in databases, you may be asking how the server obtains, stores, and locates this data.

Thus, the Internet Information Services, or IIS, serves as the operation's beating heart.

Output Caching is the name of the operation.

Even the type of file and duration of storage are customizable. by using the easy steps listed below.

  • On your server, open the Internet Information Services (IIS) Manager.
  • Access your web application by navigating through the Connections pane.
  • Give the "Output Caching" feature a double-click.
  • Examine the cached items, their expiration dates, and other pertinent details in the "Output Caching" feature.

But how can the cache be kept there?
Installing System is hence the first step.Net.Caching from the Nuget bundle

Caching in System.Web
You can implement caching within a server-side web application, usually hosted by Internet Information Services (IIS), by using the classes provided by the System.Web.Caching namespace. The caching method uses the server's RAM to cache data when you use the System.Web.Caching namespace in an ASP.NET web application hosted on Internet Information Services (IIS).

HttpRuntime.Cache.Insert("yourkey","your value");To do CRUD activities with such caches, there are a few methods under this namespace.

This is how the cache is set. You might have noticed, though, that the code above doesn't indicate when this caching item expires. This suggests that unless the web application is terminated or restarted, the caching item won't be destroyed. As a result, you must also include an expiration.

Here's another method to get there:

     string key,
     object value,
     System.Web.Caching.CacheDependency dependencies,
     DateTime absoluteExpiration,
     TimeSpan slidingExpiration

You are aware of the value and key in this case, but what about the other parameters?

Dependencies: When any of a cache item's dependencies are altered or eliminated, the cache item will be automatically cleared.

Nonetheless, if you would like it to stay in the cache until further specified expiration conditions (such absolute or sliding expiration) are satisfied or until it is manually deleted.

Absolute Expiration: The cache can have a precise expiration time that you specify. To set its value, there are three options:

  • Absolute Time of Expiration: AbsoluteTime belongs to the DateTime type. You designate a precise day and time for the cache item to expire. The cache expires when this date and time are reached.
  • Save.NoAbsoluteExpiration: This constant value means that the item will stay in the cache until it is manually removed, and it does not have an absolute expiration period.
  • Blending using Adaptive Expiration:  The slidingExpiration parameter needs to be set to NoSlidingExpiration if you are utilizing absolute expiration.

Declining Expiration
1. Sliding Expiration makes sure that the cache item lifespan will be increased by the interval value if the data is accessed within the designated time frame. For instance, a session with a 10-minute expiration is introduced.
TimeSpan.FromMinutes(5), TimeSpan.FromSeconds(30), NoSlidingExpiration, etc. are few examples.

2. Combining with AbsoluteExpiration: NoAbsoluteExpiration is required as the absolute expiration argument if sliding expiration is being used.

IIS 8.0 Hosting UK - HostForLIFE.eu :: IIS Website Debugging Using Visual Studio

clock January 15, 2024 06:43 by author Peter

Start Visual Studio: Open the Visual Studio project or solution that is associated with your IIS website.

Configure IIS: Verify that your IIS website is set up and operational. If not, set it up by making a fresh website or utilizing an already-existing one.
Build Configuration: Verify that the configuration for your project contains debugging details. Usually, the "Debug" setting would be utilized.
Begin debugging: Click on the "Start Debugging" button in Visual Studio (or press `F5`). This will connect the debugger and start your application.
Attach to Process: To attach the debugger to an already-running IIS website, go to the "Debug" menu, pick "Attach to Process," and select the process that corresponds to your IIS application pool (in most cases, `w3wp.exe} for IIS worker processes).
Choose the Appropriate Code: Verify that the source code you wish to debug is the same one that IIS is using. Make sure the right project and build configuration are chosen by checking the configuration of the solution.
Establish Breakpoints: Whenever you want the debugger to pause so you may walk through the code and examine variables, place breakpoints in your code.
Debugging: You can now debug your IIS website once it has been attached. At the breakpoints, Visual Studio will pause, allowing you to step through code, examine variables, and troubleshoot problems with the debugging tools.

Keep in mind that in order to attach the debugger to the IIS process and adjust the IIS application pool settings appropriately, you should have the required permissions for efficient debugging.

You should be able to connect the Visual Studio debugger to your IIS website in order to debug it by following these instructions.

IIS 8.0 Hosting UK - HostForLIFE.eu :: How To Remove IIS On Windows Server 2012

clock November 17, 2023 08:07 by author Peter

Today's article will teach you how to uninstall Internet Information Services 8 (IIS8) from Windows Server 2012.

Step 1
To begin, enter your password into your Windows Server 2012 as Administrator. If your Server Manager does not launch automatically after logging in, open it by clicking the first button in the task bar.

When you launch the Server Manager, the following window will appear:

Step 2
On the Server manager you will see that IIS is already installed.

To remove the IIS go to the Manage option on the upper right hand corner and click on "Remove Rolls and Features".

Step 3
Now a Window will be opened that will inform you that you are going to removing the section. Just click on "Next" to proceed.

After that you must select a Server from the Server Pool. Since I have only one Server in this article, my default Server is Automatically selected.

Step 4
Once you click Next you will get a list (Rolls) from which click on the Web Server (IIS).

Now click "Next", then one more Window will open that will ask for permission to remove the features.

Step 5
You can select the features that are associated with IIS to be removed.

After clicking Next you must give permission to restart the server automatically if it's considered necessary, then click on "Next".

Step 6
Click on the "Remove" button and the process will begin.

When the removal process is complete, your Windows Server 2012 will be restarted because you already granted permission to do so.

Step 7
After restarting it will automatically show that the removal process had completed successfully.

You can also check this on the Flag that is present on the above right hand corner. Click on the Flag and following confirmation will be shown,

IIS 8.0 Hosting Germany - HostForLIFE.eu :: How to Use LogParser to Check Visitor IPs to a Certain Page?

clock February 21, 2020 10:50 by author Peter

Today I noticed we were getting an expanding measure of spam on one of our sform pages. I was interested to check whether the majority of the client IP locations were the same (in which case I'd simply add them to the IIS IP Restrictions list). To rapidly and effortlessly make sense of this I chose to utilize LogParser.

Other than simply questioning for the page however, I needed to add an extra condition to prohibit lines that originated from a certain  internal IP address that we use for checking.

Here’s a generic version of the query I used:
LogParser.exe -q:on "SELECT * FROM x:\wwwlogs\W3SVC1\u_ex130411.log WHERE cs-uri-stem='/SomePage/' and c-ip<>'' >c:\temp\PageVisitors.txt"

I needed to see the full logged information for the request, but if I didn’t, I could have very easily just pulled the IP addresses using:
LogParser.exe -q:on "SELECT c-ip FROM x:\wwwlogs\W3SVC1\u_ex130411.log WHERE cs-uri-stem='/SomePage/' and c-ip<>'' >c:\temp\PageVisitors.txt"

You can see that I'm funneling the outcomes to a content record (the ">c:\temp\PageVisitors.txt" part) so I can without much of a stretch manage the outcomes. You might likewise need to observe that I'm utilizing the "-q:on" flag which runs the command in Quite Mode. In the event that you don't set this banner then LogParser will show comes about one page at once. At the point when funneling to a content record as opposed to the summon prompt window, you clearly can't hit a key for "next page" so without this banner the question will really hang forever if there is more than one page worth of results.

IIS 8.0 Hosting - HostForLIFE.eu :: Enable Other Protocols (TCP, PIPE, MSMQ etc.) In IIS

clock February 7, 2020 11:18 by author Peter

By default it's available only in HTTP, HTTPS and FTP protocols Windows IIS though it supports others like TCP, PIPE protocols as well.

This blog demonstrates how to enable other protocols like TCP in IIS. Getting started, we know that Windows IIS by default supports only HTTP, HTTPS and FTP protocols and you will get those protocols in the binding window of IIS.

But other protocols like TCP, PIPE etc. Can be enabled by changing IIS feature, the below steps defines how to tune IIS features to enable TCP protocols.

Follow the Steps
     Open Control Panel=>Programs=>Click on Uninstall or Change a Program=> Click on Link ‘Turn Windows Features on or off’.

  1. Windows Features window will be opened, expand .NET Framework Advance Service.

  2. Expand WCF Services=>Select All the Features HTTPActivation, Message Queuing (MSMQ) Activation, Named Pipe Activation, TCPActivation, TCP Port Sharing .Click OK button.

Windows will apply the changes you made and you will get message popup, close the window (Clicking on close button), restart your machine and follow the below steps. Open IIS=> in Connections panel=> expand Sites=>Select your website=>Go to Right site Action Pane=> click on Advanced Settings=> Expand the ‘Behavior’ section In the field ‘Enable Protocols’ set these below values by commas, (http,net.tcp,net.pipe,net.msmq,msmq.formatname). Click OK button.

  • For activating TCP protocol set ‘net.tcp’
  • For activating PIPE protocol set ‘net.pipe’
  • For activating MSMQ Protocol set’ net.msmq’

Now you are done, if you follow the above steps correctly, you will get the mentioned protocols in the binding window.

IIS 8.0 Hosting - HostForLIFE.eu :: PUT , POST & DELETE Verbs Not Allowed in IIS 8

clock January 31, 2020 11:42 by author Peter

Today, I will write about PUT, POST and DELETE verbs on the web application in IIS. And this is the error:

<h2>405 - HTTP verb used to access this page is not allowed.</h2>
<h3>The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access

After some troubleshooting the error was isolated to the actual fact that WebDav was put in on the server and was intercepting those requests for its own service use.
Rather than removing WebDav from the server, we tend to went searching for another answer. thankfully somebody on Twitter understood the problem and gave an example of changes to create to the client’s web.config get in order to disable (remove) the WebDav module for simply that specific website while not requiring any manual body actions on the server.

The code updates to create to your web.config file to resolve this error are:
      <remove name="WebDAV" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />

IIS 8.0 Hosting UK - HostForLIFE.eu :: How to Fix Troubleshoot HTTP 400 Bad Request error on IIS ?

clock November 8, 2019 10:25 by author Peter

There's a J2EE app running on the Tomcat with ISAPI redirector on IIS 8 of Windows Server 2012. Recently the customer got the error related to an AJAX request. At the point when debugging the issue, I figured out that the IIS returns HTTP 400 Bad Request error instead of passing along the url for the Tomcat to handle it.In the IIS log record, there's no record for this appeal nor lapse log not one or the other.

Go to the IIS admin:
Website > Advanced Settings > Limits > Maximum URL Segments: 32
Request Filtering module > Edit Feature Settings:
Maximum URL Length: 4096
Maximum query string: 2048

All is well. The url that makes blunder meets those design since it has recently few segments and the length is around 380 characters - a long ways behind the utmost settings. At that point I attempted to shorten the url a little bit and then a little bit.. and then finally it worked. It seems there's a limit around 300 characters.

Google around to to enable the error log and I found How to troubleshoot HTTP 400 errors. At that point go to  Error logging in HTTP APIs. Download the Enable HTTP API lapse logging  Microsoft Fix it 50634 to introduce it, yet it said the current OS is not matched! In spite of the fact that the direction applies for Windows Server 2012 Standard as the application is running on.
So have to go to regedit and configure the Http.sys registry settings with following parameters:
EnableErrorLogging: Decimal 1
ErrorLogFileTruncateSize: Decimal 10 (MB)
ErrorLoggingDir: C:\inetpub\logs\LogFiles

Then do : net stop HTTP
It will asks you to confirm another services also:
   Windows Remote Management (WS-Management)
   Windows Event Collector
   World Wide Web Publishing Service

Then do: net start HTTP
The HTTP Service service was started successfully.
Check the website, it will stop. Start HTTP again, but it said the HTTP service is already started!
So go to the services manager to start World Wide Web Publishing Service, then Windows Remote Management (WS-Management) and Windows Event Collector

Then test again and see the error log file with a record just shows a very simple error reason: URL. There's a breaking point setting called UrlSegmentMaxLength with 260 characters of course! I felt that brought about the issue in light of the fact that the full url with space name that worked when there's around 300 characters.  So go to regedit and add UrlSegmentMaxLength with 1000 characters value to the HTTP parameters and restart http, w3svc, winrm and wecsvc services again.

I ask why the MS didn't make it for an every particular site like the Maximum URL Segments and effectively to set. In any case we'll need to arrange in the Windows registry that requires to restart entire administrations and influence all sites.
