I just discovered mod_perl's internal_redirect method. I was looking for
something like that for a routine that looks up some details and then
redirects to an image file.
>From benchmarking, it's only 2% slower than directly fetching the image
file, and 7% faster than using an external direct. Further, the result
produces a "Last-Modified" header based on the final image, which is
what I want, as it allows browser caching to work on the image.
The code is also rather simple:
if ($ENV{MOD_PERL}) {
my $r = Apache->request;
$r->internal_redirect($url);
use Apache::Constants 'OK';
return OK;
}
else {
$self->header_type('redirect');
$self->header_props(
-url => $url
);
}
However, I wanted to check with more experienced modperl/CGI::App users
about this approach. I think have short-circuited the CGI::App flow with
approach, preventing "teardown" from being called. That's OK in this
case, but is there another "Gotcha" here I missed?
