Hi Andy,
Thanks for the good words!
Your problem seems to be with your provider, pages are not supposed
to have a "time limit", but if you want to have a web page refreshed
automaticly, you have to modify your page to include some kind of
refresh/reload... or deal with F5 key in your browser!
You could do some "Googling" about that to see how to manage it, as it is
a current problem for "live" sites since browsers are all trying to "save" you
money by using already cached (local) files instead of returning to website
to call a new version.
Problem is that the header of your pages have to use "expire", because browsers
check the timestamp (or expire) of your pages and if it is the same, never call
the file again, using the cached version instead.
Hope this help!
Regards,
Jacques
