Hi, to cut it short: You can ignore the PHPSESSID thing ;)
The long story, as I understood it myself:
This is your PHP Session ID and this sometimes happens, when using a specific PHP version (I think, it is 4.2.2). That version has some problems with session tracking in PHP (or ezPublish has problems to use it, i don't know).
Usually, the sessions ID is passed invisibly from the server to your browser and back (inside the HTTP protocoll calls) But in fact: ignore it. You don't need to create or call or store the URLs, that and with the ID.
Entschuldigun because of bad English! I have ez publish installed! Cube often commodity is marvelous! But in data base search routine shows it cube URL www.blabla.com/index.php/demo/blablablabla as can I this URL as for example www.blabla.com/news/ or www.blabla.com/produkts indicate! Please you help ME! I kriegt cube Kriese: -)
