MaxRequestSize communication parameter [MAXSIZE]

Usage 

HTTP, HTTPS

Values 

Size

Default 

100 kb

Description 

The size of the largest request accepted by the server. If the size of a request exceeds this limit, the connection is closed and a 413 ENTITY TOO LARGE response is returned to the client. This value limits only the size of the request, not that of the response. The value 0 disables this limit, but should be used with extreme caution. Without this limit, a rogue client could overload the server or cause it to run out of memory.
