HttpURLConnection Question

Hi, can anyone give me some info on using the HttpURLConnection object please?
I’m looking to log onto web sites using the above, but don’t know how I go about handling session cookies etc. I can isolate the cookie from the MIME header returned by the server from the inital HttpURLConnection , but each HttpURLConnection object seems to be only for one connection – how do I go about returning this info back to the server in this case?
Are there any examples/tutorials of bouncing cookies back and forth between client and server using HttpURLConnection?

All information welcomed
