Defines a "filtered" request handler, that applies an ordered set of filters (otherwise known as a "filter chain") before and after handling a request, as a means of adding a simple middleware layer to HTTP request processing.
Defines a path-matching request handler, that will match incoming requests against a set of mappings based on the URL and HTTP method, and call a handler depending on what's matched.
This module defines some path mapping functions to help test the path handler's function for registering annotated functions.
