00100                         Testing suggestions:
00101                         - Output all the values.
00102                         - In the script, make a link to the script it self, maybe add some parameters and click the link a few times so HTTP_REFERER is seen
00103                         - ALSO TRY the script from the ROOT of a site (like 'http://www.mytest.com/' and not 'http://www.mytest.com/test/' !!)

00335                 2) Then save this HTML-page and send it to kasperYYYY@typo3.com with information about 1) which webserver (Apache/ISS), 2) Unix/Windows, 3) CGI or module (ISAPI)<br>
00336                 2a) You might help us find any differences in your values to this <a href="reference.html" target="_blank">reference example</a> by comparing the values before you send the result (thanks).
00337                 <br>
00338                 3) If you are really advanced you try and click the link below here. With CGI-versions of servers it will most likely give an error page. If it does not, please send the output to me as well (save HTML-page and send to kasperYYYY@typo3.com). If you do this PATH_INFO test, please let me know.<br><br>
00339 
00340                 4) For the really, really advanced folks, it might be interesting to see the output if you could place this link in the root of a domain. That means the index.php script will be executed from eg. "http://www.blablabla.com/" and not "http://www.blablabla.com/kaspers_test/" - it can make a difference.<br>
