I do the following:
use POSIX qw( strftime );
$self->header_add(
# date in the past
-expires => 'Sat, 26 Jul 1997 05:00:00 GMT',
# always modified
-Last_Modified => strftime('%a, %d %b %Y %H:%M:%S GMT', gmtime),
# HTTP/1.0
-Pragma => 'no-cache',
# HTTP/1.1
-Cache_Control => join(', ', qw(
no-store
no-cache
must-revalidate
post-check=0
pre-check=0
)),
);
It's a whole bunch of guns, but one of them usually ends up working.
