<?php
/**
* Forces language selection via an URI parameter.
*
* This filter will detect a language setting from the URI and
* set the locale accordingly.
*
* In addition, theme URLs will have the languageid inserted into them
* so that the above processing will result in the language being set.
*
* This plugin should not be used if you are using <i>subdomain locales</i>
* (See the dynamic_locales plugin.)
*
* The URL format is:<br>
* <var>mod_rewrite</var><br>
* / <i>languageid</i> / <i>standard url</i><br>
* <var>else</var><br>
* <i>standard url</i>?locale=<i>languageid</i><br>
* Where <i>languageid</i> is the local identifier (e.g. en, en_US, fr_FR, etc.)
*
*
* <b>NOTE:</b> the implementation of these URIs requires that Zenphoto parse the URI, save the
* language request to a cookie, then redirect to the "native" URI. This means that there is an extra
* redirect for <b>EACH</b> page request!
*
* If your site will support it, we suggest you use the dynamic_locales plugin <i>subdomain locales</i> option
* instead for better performance.
