Greetings.
Seems I'm confused about how to get mod_perl to send status codes other than 200 OK.
I want to have my Perl script, upon getting the wrong CGI parameters, to give a status 404. Then, the ErrorDocument for 404 goes back to that same Perl script but with the CGI parameter ?page=error404.
ErrorDocument is currently set up like so: ErrorDocument 404 /exec/hydrogen.pl?page=error404
This works fine when I'm not having the script generate the 404 error. For example, if I visit http://foo/this_page_does_not_exist, then I get
the ?page=error404 error page. Beautiful.
However, if I access hydrogen.pl?page=this_page_does_not_exist, it needs to output a 404 status and get on with it. Presently, I just get a blank page or IE tells me there is no page.
I'm using ModPerl::Registry, so I can't just return Apache::NOT_FOUND, which is how I'm apparently supposed to do it, according to what little documentation I could find. At the moment, when the Perl script is asked for a page it can't find, it does this:
$r->status(Apache::NOT_FOUND); $r->print(); exit;
I have no idea whether this is the right way to do it. The documentation on HTTP status codes under mod_perl 2 is quite sparse.
Any thoughts?
That's the right technique, Colin. Have you imported the constant before using it?
for example see http://cvs.apache.org/viewcvs.cgi/modperl-2.0/ModPerl-Registry/t/cgi-bin/status_change.pl?rev=1.3&view=markup
