NAME

Example PerlTransHandler

Using mod_perl to rewrite URLs

Anyone that's looked at web logs will quickly see the usefulness of this little mod_perl script. It catches all requests for favicon.ico and rewrites the request to point to a vaild location. No more logs full of 404 errors.

This example is adapted from the mod_perl Developer's Cookbook, chapter 12.

file:Cookbook/Favicon.pm
------------------------
package Cookbook::Favicon;

use Apache::Constants qw(DECLINED);
use strict;

sub handler {
    my $r = shift;

    $r->uri('/images/favicon.ico')
        if $r->uri =~ m!/favicon\.ico$!

    return DECLINED;
}
1;

And configure in httpd.conf with:

PerlModule Cookbook::Favicon
PerlTransHandler Cookbook::Favicon

Although this example could easily be accomplished with Apache's mod_rewrite module, this example demonstrates how easy it is to rewrite URLs programatically, using Perl.
