i_am_jeers_colon has asked for the wisdom of the Perl Monks concerning the following question:

I'm a little vexed as far as how to go about sending an argument to my perl script in the URL. I thought I could send it like this:

<!--#exec cgi="/cgi-bin/das_counter.pl?ilikepie"-->

and receive it like this:

$pielove=$ENV{QUERY_STRING};

However, I'm getting, "an error occurred while processing this directive". What am I missing?

    you could provide us more information about what kind of error occured... you can find that in the logs of your web server.

    does your CGI program work as expected ? when run like http://localhost/cgi-bin/das_counter.pl?ilikepie do you get anything in $ENV{QUERY_STRING} ?

    assuming you're using Apache, you should try something like this:
    <!--#include virtual="/cgi-bin/das_counter.pl?ilikepie" -->

    "if you need to pass additional arguments to a CGI program, using the query string, this cannot be done with exec cgi, but can be done with include virtual" ( Apache mod_include )

    also, you'd better be using the CGI module so you don't have to mess around with (low-level) stuff like processing the QUERY_STRING.

    This worked for me. 
    <html>
<head>
<title>ssi demo</title>
</head>
<body>
<h1>ssi demo</h1>
<!--#include virtual="ssi_test.cgi?q=hi!"-->
</body>
</html>

    [download]
    ssi_test.cgi 
    #!/usr/bin/perl

use strict;
use warnings;
use CGI::Simple;

my $q = CGI::Simple->new;
print $q->header;
my $param = $q->param('q');
print qq|<h1>$param</h1>|;

    [download]
    output 
    ssi demo
hi!

      Thank you!

      The exec was the problem after all. A virtual include works fine.
