I have various sections in my site like www.mysite.com, email.mysite.com, <BR> news.mysite.com, etc all running on the same server but with different vitual IPs. <BR> that is each is configured for the port 80 and different virtual IPs. <BR> For all these sections, I need to use the same session variable to keep track of the user. <BR> How can I do it without using Cookies. For example if the user signs in from email.mysite.com <BR> and goes to chat.mysite.com, the session should be maintained. Please help me. <BR> Thanks in advance.
