set httpcontext session in javascript to be used by the server side
<p>I have a client global variable in javascript. I need to access this global variable from the server side which is living on different page. how can i achieve this without a query string? if session state required, then how can i set the session from the javascript? </p>

<p>EDITED</p>

<p>ok.. here is the full scenario..  the page itself is a sharepoint web page, i have only control on the web part. within the webpart i have a button that does window.open to open another page. Now how can i pass the javascript variable from the main page to the other page and make it accessible in the code-behind? </p>
