The AspMaxRequestEntityAllowed property specifies the maximum number of bytes allowed in the entity body of an ASP request. The default value for the AspMaxRequestEntityAllowed property is 204800 bytes (200kB).


The MaxRequestEntityAllowed property specifies the maximum number of bytes allowed in the entity body of a request. If a Content-Length header is present and specifies an amount of data greater than the value of MaxRequestEntityAllowed, IIS sends a 403 error response.


Specifies the maximum length of content in a request, in bytes. The default value is 30000000, which is approximately 28.6MB


The UploadReadAheadSize property establishes the number of bytes a Web server will read into a buffer and pass to an ISAPI extension. This occurs once per client request. The ISAPI extension receives any additional data directly from the client. The range is 0 to &HFFFFFFFF (4 GB).
