LiteSpeed comes with a persistent Perl CGI daemon which can run perl CGI script without modification, just like mod_perl in Apache.

You need to configure it as a Fast CGI application, and then add a script handler for “pl” or whatever suffixes used for Perl scripts. The Perl CGI daemon is located at

lsws/fcgi-bin/lsperld.fpl.

As “lsperld.fpl” utilizes the Fast CGI interface, you need to install Perl Fast CGI module FCGI.pm first. It is available at http://www.fastcgi.com or through CPAN(Comprehensive Perl Archive Network). The following command can be used to install FCGI.pm through CPAN:

perl -MCPAN -e 'install FCGI'

In order to deal with increasing memory usage of a persistent process, number of requests that a Perl daemon can process is controlled by an environment variable FCGI_PERL_MAX_REQ, default is 500. For example: FCGI_PERL_MAX_REQ=1000.
