parseExtensions

line:1039 at /lib/Cake/Routing/Router.php
Instructs the router to parse out file extensions from the URL. For example, http://example.com/posts.rss would yield an file extension of "rss". The file extension itself is made available in the controller as $this->params['url']['ext'], and is used by the RequestHandler component to automatically switch to alternate layouts and templates, and load helpers corresponding to the given content, i.e. RssHelper.

Method

Parameters

Return

void

Comment

Instructs the router to parse out file extensions from the URL. For example,
http://example.com/posts.rss would yield an file extension of "rss".
The file extension itself is made available in the controller as
$this->params['url']['ext'], and is used by the RequestHandler component to
automatically switch to alternate layouts and templates, and load helpers
corresponding to the given content, i.e. RssHelper.

A list of valid extension can be passed to this method, i.e. Router::parseExtensions('rss', 'xml');
If no parameters are given, anything after the first . (dot) after the last / in the URL will be
parsed, excluding querystring parameters (i.e. ?q=...).
