You could either utilize the new HTML5 local storage (only supported in the more recent/modern browsers), or you could create a session cookie in JavaScript and store the value in there.

Note that none of those approaches will affect the server side HttpSession in any way. For that you simply can't go around sending a HTTP request containing the desired information, as that's the only way to send information from the client to server side. You could however consider using ajax to send the HTTP request asynchronously and fully transparently in the background.

    Well, that's a pretty broad question. Minimum prerequirement is a moderate understanding of how basic HTTP, HTML and JavaScript work. If you already don't have a moderate grasp on them, then stop developing for a moment and invest time in learning those basic concepts. After that, look at those answers for some basic Servlet+Ajax examples: http://stackoverflow.com/a/4113258 and http://stackoverflow.com/a/4115298 The only difference is basically that you don't need to change the HTML DOM tree after retrieving the ajax response (that is, when you don't want to have any visual feedback). – BalusC Sep 24 '12 at 19:19
