This is the important point:

> and I go to an other page.

Your question is about "state". Which item the user chose on a previous 
page is a form of application state. It is your job to maintain that 
state.

Some of your options are:
- include the selected item as parameter in all requests (GET and POST, 
that means you have to add it all your links/redirects and forms as hidden 
field, this is a "stateless" approach)
- store it in http session (this is bad practice and causes other 
problems)
- store it in the browser, e.g. in a cookie or via some html5 
local-storage api

Christoph
