问题
I use JSF and I want to avoid a same session sharing 2 tabs in my browser. I think an easy way is to force url rewriting instead of using cookies.
Can anyone tell me how I can force the url rewriting with JSF?
Thanks.

Sorry, but this makes no sense. This is not something which you can control from the server side on. All browsers use the same session in all opened tabs/windows (expect of anonymized tabs/windows like Chrome Ingognito via Ctrl+Shift+N). That's just how all browsers work and completely beyond your control.
If you're having a problem with it, then you should absolutely solve it differently than attempting to disable session sharing in multiple browser tabs/windows (which simply isn't possible). It sounds much like as if you're incorrectly storing request or view scoped data in a session scoped bean. You should not do that. You should store request scoped data in a request scoped bean and view scoped data in a view scoped bean. The session scope should only be used for session scoped data, such as the logged-in user and its preferences like language settings.
I think the view scope is actually what you're looking for; it lives as long as you're interacting with the very same view (read: the very same browser window/tab) by postbacks and it it not shared in other browser windows/tabs.
