that doesnt no but at the same point it doesnt seem to work either, i can still click back through

Ok.

After some digging, Firefox has a problem with the Pagram tag (as stated above) however, it doesn't interpert the Cache-Control tag like other browsers either this should solve your problem across all browsers.

    Response.Expires = -1
    Response.AddHeader "Cache-Control", "no-cache"
    Response.AddHeader "Cache-Control", "private"
    Response.AddHeader "Cache-Control", "no-store"
    Response.AddHeader "Cache-Control", "must-revalidate"
    Response.AddHeader "Cache-Control", "max-stale=0"
    Response.AddHeader "Cache-Control", "post-check=0"
    Response.AddHeader "Cache-Control", "pre-check=0"
    Response.AddHeader "Pragma", "no-cache"
    Response.AddHeader "Keep-Alive", "timeout=3, max=993"
    Response.AddHeader "Expires", "Fri, 30 Oct 1981 05:00:00 GMT"

and still no luck - i reckon there is an issue with FF here, might drop them a line a query it as FF refuses to drop a session. (i have to refresh the home page once i have clicked logged out for it to not let me back in)

Do you have an older version of FF? Maybe v1.5? If you do test the site with that and, if it works, something changed in 2.0
