# module HTTP::Handler

##
Overview

A handler is a class which includes `HTTP::Handler` and implements the `#call` method. You can use a handler to intercept any incoming request and can modify the response. These can be used for request throttling, ip-based filtering, adding custom headers e.g.

NOTE To use `Handler`, you must explicitly import it with `require "http/server/handler"`
