Apache::PerlRun(3p)

NAME
Apache::PerlRun - Run unaltered CGI scripts under mod_perl

SYNOPSIS
 #in httpd.conf

 Alias /cgi-perl/ /perl/apache/scripts/
 PerlModule Apache::PerlRun

 <Location /cgi-perl>

 PerlHandler Apache::PerlRun
 Options +ExecCGI
 #optional

DESCRIPTION
This module's handler emulates the CGI environment, allowing programmers to write scripts that run under CGI or mod_perl without change. Unlike Apache::Registry, the Apache::PerlRun handler does not cache the script inside of a subroutine. Scripts will be "compiled" every request. After the script has run, it's namespace is flushed of all variables and subroutines.

The Apache::Registry handler is much faster than Apache::PerlRun. However, Apache::PerlRun is much faster than CGI as the fork is still avoided and scripts can use modules which have been pre-loaded at server startup time. This module is meant for "Dirty" CGI Perl scripts which relied on the single request lifetime of CGI and cannot run under Apache::Registry without cleanup.

CAVEATS
If your scripts still have problems running under the Apache::PerlRun handler, the PerlRunOnce option can be used so that the process running the script will be shutdown. Add this to your httpd.conf:

 <Location ...>
 PerlSetVar PerlRunOnce On
 ...
 </Location>
