When we upload a large file in asp.net using file upload control we got an error.so how to over come this ? The Default size of Asp.Net is 4MB. Code In Web.Config put this code.

    <system.web>  
       <httpRuntime maxRequestLength="1048576" executionTimeout="600" />  
    </system.web>  
    <system.webServer>  
       <security>  
          <requestFiltering><requestLimits maxAllowedContentLength="3000000000" /></requestFiltering>  
       </security>  
    </system.webServer>  

The below code maxRequestLength measured in kilobytes.Here is an example with a 1GB request length and a 10 minute request timeout:
    <httpRuntime maxRequestLength="1048576" executionTimeout="600" />  

 The below code maxAllowedContentLength measured in bytes. 
    <requestLimits maxAllowedContentLength="3000000000" />  

This post teaches how to fix a message: 
"ERROR: Plugin IISBinding was unable to generate a target" while enabling the SSL Certificate for your website

So, let us start.
Open IIS - Internet Information Services (IIS).

Select "Default Web Site" and click on "Bindings...."

Edit "HTTP" host to put your websitURLrl.

Insert your website URL and press "OK".

Continue the process as the original POST recommends.

Conclusion
This IISBinding error appeared to me when I moved the website from a Server to another before enabling my HTTPS certification. This solution worked for me pretty awesomely.
