I set the cookie without any problems. Even MSIE reports "accepting a cookie". The problem is that the cookie doesn't take effect immediately, but it starts "working" at the second page I go.
i.e I have a script (Perl) for logging into something like a chatroom. When registering for chat, users define what kind of chat will they use (science, romance, etc...). When someone logs in, I send a cookie to recognize his interests on my further pages and to customize colors, graphics etc. But the problem is that on the very first page after log in, the cookie is "not activated" yet. Is there any solution or what am I doing wrong.
