Alf,

Do the headers just prevent the browser from holding on to the cache and 
does the session still work? I am a little confused. I looked at the 
info on PHP.net and it confused even more.

By the way. South Africa rocks! I just spent last Christmas in Capetown 
and Langebaan with my wife. A beautiful country!
