There is no way to force the behavior, but you can exclude the HTTP
headers that tell the Web browser to not cache the pages.
Cache-Control: no-store, no-cache, must-revalidate
Pragma: no-cache
Expires:
etc.
I believe PHP may include some or all of these when you use session
management. A browser that adheres to these HTTP headers will explicitly
not cache pages, and the "no-store" directive of the Cache-Control
header actually forbids the Web browser from even storing a copy of the
resource. IE ignores the "no-store" directive and treats it like
"no-cache" instead.
I believe most (if not all) Web browsers will cache resources when not
forbidden to do so.
You should just be able to use the header() function to overwrite these
values.
Happy hacking.
