HttpClient which automatically handles cookies

Postby renegadeandy » Sat Apr 03, 2010 1:58 pm

Hey everyone,

I am trying to make an app which logs into a website and extracts some info. I am using the DefaultHttpClient however i make my post request but it doesnt seem to remember my username + password once im signed in - so i think its not storing cookies automatically.

Below is a code snippet of my app - can anybody please tel me how I enable it to store cookies automatically please!

Thanks

Andy
