Browser extension
I discussed the idea of a window id on the following page http://www.laliluna.de/articles/window-id-concept.html
and
http://www.laliluna.de/articles/2009/05/28/browser_feature_request_sample_application.html.
The window id is passed as request header “X-Window-id” and is unique per browser tabulator.
This approach allows to store data in the session per window and provides a better control in web application, if the user opens multiple window.
In my opinion, this should be solved in the browser but meanwhile we can achieve this using a browser extension. I have written one for Firefox and are planning to write one for IE and Safari/Chrome as well.
The extension is published under the [RobinHood licence 0.1](http://www.laliluna.de/open-source-robin-hood-license.html).
There is a usage limit only for companies and organizations. A licence is required, if your company’s turnover or organization budget exceeds a limit of 2 million Euro.
Install Window Id Extension!
(Browser might block install, Check the info area at the top of the browser)
