Connection with a web server

Hi, I would like to do the following for my project:

--connect my game the a web server
--send players' (from multi-machines) result to the server
--rank players according to the result
--get the ranking from the web server and display it in the GUI.
--provide instantaneous update (if possible)


I have done some research about the relative topic, but didn't find much useful information.

is anyone here know any resources or tutorials or have an idea where to start?

Thanks a lot!!
