使用Web服务器时维护会话

Question

I am using the simplest way to maintain sessions, which is:

Just create 1 HttpClient and use it for every server call, which will automatically handle cookies etc..,

But the problem here is, when i close the application, the HttpClient object is being destroyed, as expected and hence i cannot login.

So i fixed it, this way:

Store user-email and password in shared preferences, every time the application is launched make a call to the login function(this creates a new session) and use the same HttpClient.

The problem here is, every session in the web server has an expiry duration of 3 years. Where as i am creating a session (Since i am calling login every time user launches the app), every time user launches the app. Which causes session duplication or say unnecessary sessions being created on the server side.

Am i doing it the right way? How can i solve this?

Thank You

Just implement your own CookieStore. It's pretty easy: Extend BasicCookieStore, instantiate it and pass it in the HttpContext. You can store it against a sqlite database, or even just dump it to an xml file (but sqlite is lighter). I have it working here, but I don't time to sanitize the code right now.
