IIS upload not happening for larger files (>650MB) for IIS 7.5 RRS feed

  • Question

  • We have developed an ASP.NET application that receives uploads from another component. The upload seems to be working fine for smaller files( below 650 MB). But when the file is larger than 650, the upload fails and even the action method is not being executed in the class.  Is it possible to do an upload of around 2GB using this version of IIS ?

    Thanks in advance,

  • Hi Narendra,

    Welcome to the MSDN forum.

    To solve that issue, please check this similar issue and try to modify the web.config:


       <!-- maxRequestLength for asp.net, in KB -->

       <httpRuntime maxRequestLength="xxxxx" ></httpRuntime>





             <!-- maxAllowedContentLength, for IIS, in bytes -->

             <requestLimits maxAllowedContentLength="xxxxxxxx" ></requestLimits>




    For more detail information about the ASP.NET development, please redirect to this appropriate forum: https://forums.asp.net/for better support, thanks for your understanding.
