I, rather blindly, put a reference to a hash of the HTTP headers and hash of
the CGI params in pnotes for most requests.
Technically, a poorly formed loop might DOS a child if the number of params
or headers is evilly large.
For instance, someone silly could write
my $params = $r->pnotes('params');
foreach my $key_1 (keys %$params) {
foreach my $key_2 (keys %$params) {
next if $key_1 eq $key_2;
warn "duplicate message from $key_1 and $key_2" if $params->{$key_1} eq
$params->{$key_2}
}
}
Of course that's silly code, but, looping over the params or headers is
certainly not an impossibility.
Do I need to, should I do any checks before stashing these values in pnotes?
Thx
