 * Allow the session proxy to time out after 15 minutes.
 * This program now requires PHP v4.3.0 or newer due to bugs in the socket
   functions of PHP 4.1.  ctdlheader.php now enforces this.

 Revision 1.4  2003/11/01 06:12:20  ajc
 * Got login/logout working.  Still need to redirect unloggedin sessions to
   a login page.

 Revision 1.3  2003/11/01 05:10:49  ajc
 * When sending the QUIT command to the server, output a bunch more newlines
   so the session proxy has a chance to see that the Citadel server closed
   the connection.  This will make the proxy shut down as well.

 * Stabilized the session proxy
 * Added 100 mode text downloads
 * Print server hello banner
