Hello, As far as I know, the session will use a cookie, and the cookies are linked to one domain name. I don't know a way of using a cookie accross multiple domains, but I guess this should be possible. The question is : will PHP allow you to do that? I guess no because this could be a security issue... maybe someone in the list can help. search the web for the cookie accross multipple domain.

The script is executed successfully but it does not seem to recognize the $_SESSION to show that I'm logged in. When I surf to http://www.groep6049.ksjnet.be/index.php and try to login it works perfectly. Is it possible to set something extra in my php session variables to make it work when surfing directly to http://www.ksachiropoelkapelle.be <http://www.ksachiropoelkapelle.be/> ? Or do I have to disable the cloaking? Thanks in advance, Reinhart Viane -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
