title: php sessions and mobile applications
body: <p>I'm developing application that would communicate with a mobile app. My problem is as follows - my mobile app doesn't accept any session data - no $_GET variables, no cookies - all communication in both sides is done with xml and I can't change it by, for example adding some parameters to xml, because mobile app would not understand those. Now, I would like to use php sessions - mobile app sends me a unique identifier which I can use as a session key. Will this work in an usual manner, like setting some variable in $_SESSION array, and then retrieving them in next request?</p>
  
  <p>ps. I can't use database nor files...</p>
