This route is meant for being called prior to retrieving of the request body. It inspects the Content-Length header and determines if the request should be allowed to proceed. The limit can be made variable by supplying a function to the limit argument returning a numeric. If the Content-Length header is missing and the limit is not Inf the response will be set to 411 - Length Required, If the header exists but exceeds the limit the response will be set to 413 - Request Entity Too Large. Otherwise the route will return TRUE and leave the response unchanged.
