title: Codeigniter Session class disable for particular controller
body: <p>I'm having application in codeigniter already, now i'm developing the android from this application. Using this application as a server side and doing client console in android. In server i'm maintained the session. But in android request i can't maintain the session. Instead of that i'm creating GUID in server at the first request of login request and storing at client side and also storing at customer table, afterwards for each request client will send the GUID for authentication. 
  Now what is my problem is each request getting from android codeigniter create session with different session id(each request generating new session id). How to avoid creating session and storing into database.(Only for android request, but browser request it have to store)</p>
