[symfony-users] Re: Race condition with session data
The site needs to work with javascript disabled so unfortunately that's not an option at present. Adding a delay seems a bit of an unreliable way to work around the problem due to not being able to guarantee how long A1 will take to finish sending content. Is there definitely no way to force a session write from an action? Would calling $this-getUser()-shutdown() do it?

The answer is: yes - $this-getUser()-shutdown() seems to work. If anyone knows of a particular reason why this might be a bad idea, please let me know.

Re: [symfony-users] Re: Race condition with session data
This is not a bad idea and in fact we have used to prevent session write locking as we would have multiple ajax requests running on a page load each with semi-lengthy processes running that would force the ajax requests to queue instead of run asynchronously because of session write locking. By calling $this-getUser()-shutdown() you are forcing symfony to write to all data sent via $this-getUser()-setAttribute() to the actual session variables. Just remember. Any $this-getUser()-setAttribute() calls will not work after calling shutdown() because you will be storing the variables in symfony's session placeholder that never gets written to session because you have already called shutdown().
