Here's what I do in my autohandler:
$r = $m->apache_req;
if ( i don't want this page cached... typically all .html pages ) {
$r->no_cache( 1 );
}
elsif ( i do want this page cached... typically all .css and .js
pages ) {
$r->header_out( 'Cache-Control', "max-age=" . 86400 );
}
where '84600' is the number of seconds to cache (i.e., one day in this
case).
