Turning off a perl handler in a particular directory

[Chris Brooks <cb...@carescout.com>]

Good morning all,

I have a couple of perl handlers (AccessHandler and Wrapper) running at the document
root of my mod_perl server.  I need to turn one of those handlers off in a lower
level directory, but keep the other one running.

Here's the relevant text from Apache's config file:

<FilesMatch "\.(htm|html|pl)$">
    PerlFixupHandler Carescout::AccessHandler
</FilesMatch>

<Location />
        SetHandler perl-script
        PerlHandler Carescout::Wrapper
        PerlSendHeader On
        Options ExecCGI
</Location>

I tried setting the PerlHandler back to cgi-script (in the lower-level directory),
but that did not turn the Wrapper handler off:
<Location /www/perl/htdocs/lower_level>
        SetHandler cgi-script
        PerlHandler Carescout::AccessHandler
</Location>

Any suggestions on how to do this?

Thanks,
Chris

Looking at p. 444 of the Eagle book seems to indicate that this is right
thing to do (see http://www.modperl.com/book/chapters/ch9.html#item_handler):

# in httpd.conf:

<Perl>
    package Apache::Reset::To::CGIScript;
    use Apache::Constants 'DECLINED';
    
    sub handler {
        shift->handler('cgi-script');
    
        return DECLINED;
    }
</Perl>

<Location /store>
    PerlFixupHandler Apache::Reset::To::CGIScript
</Location>



Good luck.

You're absolutely right, the mistake is mine.

I have tried writing the config files a couple of ways:

<Location /store>
        SetHandler cgi-script
</Location>

and

<Directory /www/perl/htdocs/store>
        SetHandler cgi-script
</Directory>

I have not had luck in either case turning off the Wrapper handler.

I did not encounter any errors in restarting the server with the PerlHandler
Carescout::AccessHandler statement.

Thoughts?

Thanks,
Chris

That should probably be Directory. As written, it will do this for
http://www.yourdomain.com/www/perl/htdocs/lower_level/ ... Or is that what
you meant? (I.e., Is this a mistake in your email, your httpd.conf, or
my assumptions?)

          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is only relevant when the handler is perl-script. I would have imagined,
completely without evidence of course, that this would have given you an error
when Apache parsed the file. (Unless that was supposed to be PerlAccessHandler.)
