Fellow Monasterians,

I'm having a hard time getting my head around sessions.

Background: using CGI::Application, CGI::Application::Session, and CGI::Application::Redirect on a dedicated Linux server.

Scenerio:

  1. I set a session param in one of my modules and then...
  2. redirect to an instance script in the web root that...
  3. calls another module that uses the value in the session param

Problem: The session param in Members.pm is undef.

So, what am I not getting/understanding about sessions? Thank you!
