Configuring mod-Perl to handle only some file types

Hello,

I have a mod_perl program that is written to handle URL's that
name either a directory or *.html type files. All other types
I want Apache to just do its regular thing (e.g., serve image
type files, or .doc, .pdf, .js, .css, etc.) 

What's a good way to configure that? So for an entire website 
directory, and all its substructure, my perl handler gets only directories
or  *.html files, and apache handles everything else without
involing my perl handler.

Thanks for any help or ideas.

Hi Joe,

I used .cgim extension for this to reflect mod_perl

I don't have access to an example from a more recent server but this is 
how I made .cgim's under one site work.  It might help you.

<Directory /htdocs/example.org/html/>
   <Files ~ "\.cgim$">
     SetHandler perl-script
     PerlHandler Apache::PerlRun
     #PerlHandler Apache::Registry
     Options +ExecCGI
     PerlSendHeader On
     PerlInitHandler Apache::StatINC
     PerlSetVar StatINC_Debug 1
   </Files>
</Directory>

regards,
KAM

Joe,
I don't think that that approach will work in the long term. What if
someone wants to serve a file *.xyz in the future? You would have to
adjust  that regex. And again, and again...

I think it would be much easier to set up <DirectoryMatch 'regex'> and
<FilesMatch 'regex'> sections for what you want to serve by your
handler(s), and let Apache handle _all_ other files/dirs.

Filter on what is the smaller set - and I think that's your dirs and .html
files. All other files not mentioned in those <*Match ...> sections are
automatically handled by Apache. Further - a regex matching all those files
you don't want to handle yourself would be rather lengthy and unwieldy.

Take a look at Apaches fine documentation, look for <DirectoryMatch ...>
and <FilesMatch ...> directives.
http://httpd.apache.org/docs/2.2/mod/core.html#directorymatch
http://httpd.apache.org/docs/2.2/mod/core.html#filesmatch

For example, a <FilesMatch ...> for . htm or .html Files would look like
(untested):

    PerlRequire /var/www/mysite/cgi-bin/my_modperl_module.pm

    <FilesMatch "\.html?$">
        SetHandler perl-script
        PerlResponseHandler my_modperl_module   # which contains a sub
handler {...};
    </FilesMatch>

Cheers,
Ekki

Thank you – both Kevin and Ekki 

For my purposes I think Ekki’s idea sounds more like it could work.

Ekki – would you know how to phrase that match in the negative?
In other words, write a regex to match .jpeg, .doc, ....etc. etc.
and if those matches FAIL - then use perl handler?

Thanks again,
Joe N

I just used a <FilesMatch> section in httpd.conf. Like so:
        <FilesMatch "\.(tx|html\...)$">
                SetHandler perl-script
                PerlResponseHandler TxShow
        </FilesMatch>

This match expression filters out any files that either end in .html.?? or .tx.??, the two ?? being language extensions used for auto negotiation.

You can build nearly any kind of Regex there to filter out what you want handled by your mod_perl script and what should be handled by Apache directly.

Cheers,
Ekki

I just used a <FilesMatch> section in httpd.conf. Like so:
        <FilesMatch "\.(tx|html\...)$">
                SetHandler perl-script
                PerlResponseHandler TxShow
        </FilesMatch>

This match expression filters out any files that either end in .html.?? or
.tx.??, the two ?? being language extensions used for auto negotiation.

You can build nearly any kind of Regex there to filter out what you want
handled by your mod_perl script and what should be handled by Apache
directly.
