How to control the Request Size and Execution Timeout

Limiting the Request

You can apply the below limits on the request:

• Request size; default is 28.6MB in IIS 7.0 and 4MB in IIS 6.0. Please see below.
• Request header size
• Url length; default is 4KB
• Query string length; default is 2KB

Max Response Size

• Response size by default doesn’t have a limit from the server point of view.

• The client, however, can limit the response size by setting “content-length” in the request header.

• If very large data required, we should be considering compressing the data or returning binary data. How large is very large?! Perhaps above 50MB.
