If you want to set the maximum request size, e.g. to define the maximum size for file uploads, you can use the way described in this post:

This command line tool just adds a new node to the web.config file of the target application. This node is added to the <system.webServer> section:

        1: <security>

       2:     <requestFiltering>

       3:         <requestLimits maxAllowedContentLength="52428800" />

       4:     </requestFiltering>

       5: </security>

The value of the maxAllowedContentLength attribute is the number of bytes for the request.
If you want to allow 50 MB file upload this means 1024 x 1024 x 50 = 52428800
