sizelimit_route: Limit the size of requests

In routr: A Simple Router for HTTP and WebSocket Requests

Limit the size of requests

Description

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.

Usage

sizelimit_route(limit = 5 * 1024^2)

Arguments

limit

Either a numeric or a function returning a numeric when called with the request

Value

TRUE if the request are allowed to proceed, or FALSE if it should be terminated
