This is sort of a weird situation, so here's a bit of background. We have a machine that hosts quicktimes offsite. That machine runs a mod_perl handler that attempts to keep the quicktimes from being deeplinked. One of the other things it does it handle requests from the user-agent "contype" by only sending headers, instead of attempting to send the full file back. contype is this weird plugin holdover that uses GET, but doesn't actually examine the file that's returned, just the headers, you can find out more about it on google if you care.
Anyway, in mp1 this was handled just find and dandy by using send_http_header. But that's gone in mp2. I would set $r->content-type, but i don't want to make the assumption that the file is a quicktime. Any ideas? adam
