View source for SoC php sessions

<center>(Return to the main idea page for the [[Google Summer of Code]])</center>

== Overview ==
Geeklog currently uses custom session management to maintain users session information. The custom session implementation is antique and needs to be upgraded to a fully supported session management system such as the one provided by [http://www.php.net/manual/en/book.session.php PHP Sessions]. The implementation needs to be secure and should cache user data between page loads of a session.

== Objective ==
Implement new session handling in Geeklog.

This project could be extended by adding the ability for Geeklog to support http and https for the same site. By forcing logged-in users to use https, session hijacking can be prevented.

== Level of Difficulty ==
''medium to high''

Geeklog's existing session software must be understood before being replaced. Student's taking on this project will also have to ensure plugin compatibility with the new session implementation.
