Problems with Caching

I have session caching set to private. However, when I log back in to my site, it wants to show the cached page, even if i've made changes to my account, or whatever. Another example: I log in as Kit, do some things in the site, logoff, then log in as Erica. The site wants to show me as logged in as Kit until I refresh the screen a time or two. Another problem exists within this one: If I turn caching off, this problem is fixed, however, I can't hit the back button on the browser without it telling me the page has expired and I need to hit refresh to reload the information. Any help is much appreciated. THANKS, Kit _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
