Sessions interfering with one another

Hi All I am having a problem with two pieces of software written in PHP interfering with each other's sessions. That software is Squirrelmail, and another piece of software I have written (a web-based administration site for schools). I think part of the problem might lie in the cookies that are being set. Squirrelmail exists at: https://blah.server.com/squirrelmail/ and the other piece of software resides at https://blah.server.com/ict/. So I figure perhaps cookies are overwriting each other because they are being set for blah.server.com and not the whole path. I am using PHP4 sessions. Is there any way I can make these two sessions distinct? The problem is these sites are often used at the same time, in different windows. In fact my site often launches Squirrelmail, and at that point they automatically lose their login to my site because the cookie disappears!
