 * There are three ways to call webmail.php

 * 2.  webmail.php?right_frame=right_main.php&sort=X&startMessage=X&mailbox=XXXX
 *      - This loads the frames starting at the given values.
 * 3.  webmail.php?right_frame=folders.php
 *      - Loads the frames with the Folder options in the right frame.
 *
 * This was done to create a pure HTML way of refreshing the folder list since
 * we would like to use as little Javascript as possible.
 *
 * The test for // should catch any attempt to include off-site webpages into
 * our frameset.
 *
 * Note that plugins are allowed to completely and freely override the URI
 * used for the "right" (content) frame, and they do so by modifying the 
 * global variable $right_frame_url.
