Re: [fw-mvc] Zend_Controller_Action_Helper_Redirector kills thesession

Putting code in a dispatchLoopShutdown would not help at all, the script exit/die in the redirectAndExit function.

So the only way to have some  bits to be executed is the register_shutdown_function.

 

About session_write_close, this call is here to prevent a bug regarding session persistence when redirecting. In some cases, when doing a redirect the session variables may not be saved, and this method helps a lot with loosing data in session.

 

Regarding your problem, I think that adding an option to handle the case when the session_close should not happen could be a good solution. The default behavior would remain the same, that is calling the session_close.

As specified in the blog post I'm not interested in using Zend_Session.

This post was more about why the Redirector helper actually kills the
session, and if people thinks this is good practice. :)
