You've discovered a feature of PHP; this is not specific to CakePHP. Only one request can use the session at once. (And CakePHP does like to use the session.) If you are certain your requests do not need to use the session, tell PHP not to open the session in the first place. Or if you can get any required info out of the session up front and then close the session while you do your database queries for the results (if you're sure you don't need to write anything to the session later), then you can tell PHP to close the session early, instead of waiting for PHP to close it for you at the end of the request, and thus allow the next request to start more quickly. http://www.thedeveloperday.com/anti-asynchronous-ajax-calls-and-php-sessions/ -- Our newest site for the community: CakePHP Video Tutorials http://tv.cakephp.org Check out the new CakePHP Questions site http://ask.cakephp.org and help others with their CakePHP related questions.
