I have updated (AddHandler) the Apache httpd.conf to execute only .pl

<Directory "mydir/tools/cgi-bin">
    AllowOverride AuthConfig
    Options FollowSymLinks
    Order allow,deny
    Allow from all
    AddHandler cgi-script .pl
</Directory>
[download]

But still getting the same error. I am new to Apache configuration ...anything else needs to be done.. Thanks again...
