HTTP authentication

filed under: @ 10:38:03

I've added a printer friendly button on the studies pages. Some very simple PHP and the bit of mod_rewrite in the .htaccess file to keep the URLs clean. I also found out a way to force IE to forget the credentials used in an Apache based HTTP authentication, making log out possible (see article for details):

<script type="text/javascript">
var agt=navigator.userAgent.toLowerCase();
if (agt.indexOf("msie") != -1) {

Adding also a redirect it's possible to have a log out button that actally acts like a proper one, except that it still prompts for a user and password window that needs to be canceled.
Tested only on Firefox and IE6 running on Windows XP.
