Option Name:request_header_max_size
Default Value:request_header_max_size 64 KB
Suggested Config:

	This specifies the maximum size for HTTP headers in a request.
	Request headers are usually relatively small (about 512 bytes).
	Placing a limit on the request header size will catch certain
	bugs (for example with persistent connections) and possibly
	buffer-overflow or denial-of-service attacks.
