I have a file (login.php) that will not save new PHP session variables. There is scripting that accesses an API using fsockopen via a https connection. Could this be the issue?

It's only this file, when that file is included. Any other time it saves just fine.

But no matter where I set the variables, be it before the file is included, after, during, it all just acts like nothing happened when I access a new page.
