maxAllowedContentLength do not work for IHttpHandler IIS7

Question

I have ASP.NET IHttpHandler module which handle file uploads. I set file size limit to 50mb in config file

  <system.webServer>
   <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="52428800" />
      </requestFiltering>
    </security> 
  </system.webServer>

But still get error while uploading 13mb file.

System.Web.HttpException (0x80004005): Maximum request length exceeded.

How to increase default allowed file size?

To summarise, to raise the file upload size to 50 MiB in IIS7 add the lines below in the correct section of the Web.config file:

  <system.webServer>
   <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="52428800" />
      </requestFiltering>
    </security> 
  </system.webServer>

and

  <system.web>
    <httpRuntime maxRequestLength="51200" />
  </system.web>

1024 X 1024 X 50 = 5242880 bytes in 50 MiB

1024 X 50 = 51200 KiB in 50 MiB

This is actually wrong - http://stackoverflow.com/a/3787284/ - you need kilobytes here. – sharptooth Aug 06 '13 at 07:27
Corrrect maxRequestLength is in KB see here: http://msdn.microsoft.com/en-gb/library/e1f13641%28v=vs.85%29.aspx – AJ Dhaliwal Jan 06 '15 at 13:18

For classic ASP users also check this settings in addition to the web.config settigns:

IIS > CLick on Website > ASP > Limit Properties > Maximum request entity body limit
