title: keep "session only" cookies, iOS
body: <p>I'm creating an app that connects to a website, and I don't want the user to need to enter their user credentials every time the app loads. The website returns a session cookie (no expiry date set). Is there any problem with me holding on to that cookie indefinitely? If I just reload it when the app starts, it seems to work.</p>
  
  <p>Thanks!</p>
