Shared PHP Sessions Across Multiple Virtual Hosts

[megashell]

Hi,

 

So I'm having an issue where I have several virtual hosts set up on my server.  Example:

 

localhost (points to htdocs/blah)

localhost:100 (points to htdocs/asdf)

 

localhost has session data that needs to be accessible in localhost:100

 

On my computer, I tested it and it works fine.  I set some session data through localhost/file.php.  Then, I go to localhost:100/test.php, start the session, and the data is there.

 

However, on our working server, this is not the case.  After setting the data and going to localhost:100/test.php, it clears out all the session data.

 

It's as if PHP is recognizing it as a new domain and generating a new SESSID, but the browser sees it as the same in the cookie.

 

ALl that is needed to reset the session data is session_start();.

 

Ideas why it works on my computer but not the server?

One note:  It isn't actually changing the session ID.  They remain the same between localhost and localhost:100, however the contents of $_SESSION is cleared out
