Hmm... First of all, the Guide (and experience :-) sez that IMMEDIATELY
after running
$r->internal_redirect(blah);
one should
return OK;
Secondly, I would suggest doing it differently:
tell the request object that the handler returned code 503, and in
httpd.conf:
ErrorDocument 503 /DBConnectError.cgi
I just wrote this handler in 2 minutes, that demonstrates:
=========
package Stat::Testfail;
use strict;
sub handler {
my $r = shift;
$r->status(503);
return 503;
}
1;
=========
with the following httpd.conf entry:
<Location /testonly>
SetHandler perl-script
PerlHandler +Stat::Testfail
</Location>
and it works like I've described:
# telnet localhost 80
GET /testonly HTTP/1.0
HTTP/1.1 503 Service Temporarily Unavailable
Date: Tue, 03 Apr 2001 18:01:28 GMT
Server: Apache/1.3.9 (Unix) (Red Hat/Linux) mod_perl/1.25
Connection: close
Content-Type: text/html
<HTML>
<HEAD><TITLE>An Error Occurred</TITLE></HEAD>
<BODY>
<H1>An Error Occurred</h1>
503 Service Temporarily Unavailable
</BODY>
</HTML>
(Naturally this would have been different if i'd set an ErrorDocument 503).
HTH!
L8r,
