Apache must be configured to handle Mason much as with Embperl. We will choose a directory and for all .html files under that directory, have Mason process them (for the same reasons, too). First, create a directory for the Mason work: $ mkdir /var/www/html/mason $ chmod a+rx /var/www/html/mason As root , add the following to /etc/httpd/conf/httpd.conf : PerlSetVar MasonCompRoot /var/www/html/mason PerlSetVar MasonDataDir /var/www/misc/mason PerlModule HTML::Mason::ApacheHandler <Directory /var/www/html/mason> SetHandler perl-script PerlHandler HTML::Mason::ApacheHandler </Directory> The first line sets the Mason component root directory to /var/www/html/mason . This tells Mason where to find the components (more on these later). The data directory is set to /var/www/misc/mason . The Mason data directory should not be under the HTML root directory ( /var/www/html ), because we want to hide the Mason data files from the Web surfer visiting our site. The data directory contains data files that Mason uses, so we have picked an innocuous place for Mason to put them. You do not have to create this directory; it and all of its subdirectories are magically created for you. Apache directives should be defined for the directory /var/www/html/mason . They tell Apache to set the handler to perl-script and to use the HTML::Mason::ApacheHandler module for all files in the /var/www/html/mason directory.
