Slightly off-topic... Consider changing

    if (!(substr($Request->ServerVariables("SERVER_NAME")->item(),0,3)
+ eq "www") && !(substr($Request->ServerVariables("SERVER_NAME")->item
+(),0,3) eq "mlx") && !(lc($Request->ServerVariables("SERVER_NAME")->i
+tem()) eq "localhost"))

to

    my $svr = $Request->ServerVariables("SERVER_NAME")->item();   
    if ((substr($svr,0,3) ne "www") && 
        (substr($svr,0,3) ne "mlx") && 
        (lc($svr) ne "localhost"))
