    httpd security and authentication settings. Do this only if your server\n
    software is unable to indicate that a safe redirection was done and\n

    accessed by anyone. (See the doc_root and user_dir options in the\n

    The short form is \"<? code; ?>\", while the long form is\n
    \"<?php code; ?>\".  If you plan on using XML on your site, you\n
    should disable the short form. This is the default and can be overridden\n
