return value for response handler

[John ORourke]

Hi folks,

I had a bug with an interesting side effect which I want to understand.

I wanted to redirect the user's browser, and in my response handler I 
was setting $r->status(302) but returning Apache2::Const::OK instead of 
the correct Apache2::Const::DONE.


This caused Apache to perform an internal redirect.  Can someone explain 
what was happening in terms of handlers and subrequests or point me to 
the right doc page?


thanks
John

This is just a guess. So it may be completely wrong. But good old CGI allows 
you to send "Status: 200" along with a Location header to perform an internal 
redirect.

mod_perl does the same if the perl-script handler is used and PerlOptions 
+ParseHeaders. So I'd dig in that direction if that matches your setup. 
Otherwise it is probably an Apache thing.

If you find out what it was tell me, please.
