Clearing Browser's Cache on Log out

How do I implement a public/shared computer option?

[annefromuk]

I was wandering how Hotmail clears the browser's cache when you sign out?

Because I would like to give my users this option when they log into my site from a public computer.

Also is there a way to send diferent bookmarks to be stored in favorites instead of the URL they are currently viewing, because if a user does not accept cookies they will have a session ID stored in the URL and I do not want this to be stored in the users favorites for security reasons.

In adition to the Bookmarks can I alsp store a diferent URL in the Browsers History instead of the URL with the Session ID, again this is to increase my sites security.

As an example to my two last questions, I would like
domain.com/news/?sid=123e4
to be stored in History/Favorites as
domain.com/news/
(I currently use mod_rewrite to hide the fact I use PHP scripts)

Thanks

There are some metatags that specify the way the browser handles page caching. You can find more info on this topic here : [web.archive.org...]

With a DHTML/javascript method for internet explorer you can specify the exact URL and the title:
[msdn.microsoft.com...]

Syntax : external.AddFavorite(sURL [, sTitle])

Good luck!
