title: iPhone problems with PHP sessions
body: <p>This is something that I in practice so far I have not seen before.</p>
  
  <p>I made a web app which works beautifully on all devices (so far I was thinking). Last week I received a few complaints that one part of the application does not work. Maybe I've reviewed over 100 times my code and I have not found a mistake and error behavior is that at one point the session expires or is just is not setup - which is not possible. The system was tested on a pile of users.</p>
  
  <p>Today I received a response from a client that uses the iPhone 5. And really happens is that sessions are not working properly.</p>
  
  <p>I use this session to force the user to open the pages in the order and that there is no possibility of jumping from page to page. If the user tries to skip the page, just go back to the beginning and need to re-start the process.</p>
  
  <p>On the iPhone during the process returns me to the start and stop. It does not allow you to go to level 1 just returning back until you clear you cache.</p>
  
  <p>This error happen randomly anywhere in process.</p>
  
  <p>-To mention, I sessions not deleted until the user reache the end.</p>
  
  <p>Is it possible that the iPhone has a problem with their browser or is error on my side?</p>
  
  <p>Thanks!</p>
