you can't do that with mod_perl 1.0 - you can $sub->run() but that result

For comparison, how would you do this in mp2? With a filter?
pretty much. I believe that subrequests in apache2 have the same
limitations as before wrt calling run(). but if the main reason you want to
capture a subrequest is to post-process dynamic content then you can simply
insert an output filter to do that for you, as that is what they were
designed for.
Nah, you can do it in a much cleaner way in mp2.
See http://perl.apache.org/docs/2.0/api/Apache/SubRequest.html#C_lookup_uri_,
but basically you can
my $data; my $subr = $r->lookup_uri($uri, $filter); $subr->run;
And $filter can be a very simple output filter that just stashes data as it
comes out or anything else you feel like doing.
Hmm, and where do you get this $filter object from? Do you have a working example?
Hmm, I think you just got me there. I didn't think long enough before answering
that one ;-)
I can see why one can't do that now that I've looked at code for a few minutes,
and sorry for misleading anybody on this one.
Ah, no, I think it's quite do-able, I just thought that you had an example at hand. The $filter argument is just a pointer to somewhere in the filter chain. So I suppose on could add a filter for the subrequest and pass $filter: $subr->output_filters. But as I don't have a test, I can't vouch for it to work. If you want I can write a test for it later, but now I need to resolve if a few other issues first. So let me know if you want me to work on this.
