limit_request_line --limit-request-line INT 4094 The maximum size of HTTP request line in bytes. This parameter is used to limit the allowed size of a client’s HTTP request-line. Since the request-line consists of the HTTP method, URI, and protocol version, this directive places a restriction on the length of a request-URI allowed for a request on the server. A server needs this value to be large enough to hold any of its resource names, including any information that might be passed in the query part of a GET request. Value is a number from 0 (unlimited) to 8190. This parameter can be used to prevent any DDOS attack.
