My question is inspired by an old problem that I don't think I properly resolved. I was storing array information in a Joomla session which I accessed a short time later. I found that intermittently the Joomla variable I had set was missing.
For interest you can see my original problem at https://stackoverflow.com/questions/13052495/how-to-prevent-race-conditions-when-writing-reading-joomla-session-variables-fr
I'm not going to ask the same question though, instead I was hoping to get answers for the following related questions.
- What could cause Joomla session data to intermittently go missing?
- How could I troubleshoot missing Joomla session variables?
