suppose i wanted the same logic as:
return Apache::DECLINED unless $r->is_initial_req;
except that sometimes it may be necessary to serve for a subrequest, just not more than once. the construct i tried is:
for (my $pr = $r; $pr; $pr = $pr->prev) {
if ($pr->notes->get(__PACKAGE__ . '::SEEN')) {
$r->log->debug("We've been seen already.");
return Apache::DECLINED;
} }
$r->notes->set(__PACKAGE__ . '::SEEN', 1);
That's because you are setting that SEEN flag in the subrequest itself, and that subrequest will most likely be short lived. Nobody will see that flag, unless that subrequest fires off another subrequest of it's own.
What you are trying to do is probably :
$r->main->notes->set(__PACKAGE__ . '::SEEN', 1);
And then your check becomes
$r->main->notes->get(__PACKAGE__ . '::SEEN');
Without a need to cycle over the requests list either.
