no-store no-cache ? :-((

Hi, when I access my php-webservice (its for search Courses in a learning management system <- there the server is located, too), I got the following errormessage to my client : HTTP/1.1...... Server: Apache/1.3.29 (Win32) PHP/4.3.3 X-Powered..... Expires: Mon...... Last-Modified: Sat..... Cache Control : no-store, no-cache, must-revalidate Cache-Control : post-check=0, pre-check=0 Pragma: no-cache Set-Cookie : SID=4fdfdf3frwe435sdfd45433wfedfesf4; path=/ Status: 302 Found Location: http://<substitute-myserver>/Suchdienst.php?set_Lang=&SID=4fd....... Connection: close Content-Type: text/html Well, it works fine if i am testing it without a necessary header. That header (require_once .....) points to a file, which itself points to a bunch of other files, it depends on (well, I am trying to get the Web Service working with ILIAS2.4beta and ILIAS3alpha..... hell this sucks). I am pretty happy, because I need acutally only the mysql functionality from that file in the header - i will probably cut that off the file and copy the functionality in my own file. But I haven't tested this, yet - and I am afraid - the copy may also not work for me. I am also not sure, if missing memory or cache is really the problem hier. So here s my question : Could someone tell me the reason for the problem above and how I may solve it. It would be a nicer solution for me, if I could simply increase the memory for the Web Servie somehow. Please help ! Thanx ! Regards, Arne
