title: Maintain PHP Session in web app on iPhone
body: <p>I have a jquery mobile web app.  On my iPhone when I am on the web app I have a login and session variables.  If I leave the app to go to another location on the phone and then return to the web app, I have to log in again.  It seems like the session is not maintained.  Further if I have an external link and it opens safari for that link, that same session is not transfered to the safari window.  Is there a way to maintain the session?</p>
