sizelimit_route {routr}

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.

sizelimit_route(limit = 5 * 1024^2)

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