Hm, I don't think so. The connection is made by a so called XMLSocket in Flash, it's a socket that sends and receives string data (XML mainly, but any string is fine, as long as you don't let Flash parse it, but here it is automated because the request gets out before you actually use your socket connection).

So, what I have is
Code:
open POLICYFILE, "<$filePath" or die "Can't open '$filePath': $!\n";
$content = <POLICYFILE>;
close POLICYFILE;
...
print CONNSOCK $content;
print CONNSOCK $NULLBYTE;
close CONNSOCK;

in the standalone script versus
Code:
open POLICYFILE, "<$filePath" or die "Can't open '$filePath': $!\n";
$content = <POLICYFILE>;
close POLICYFILE;
...
print STDOUT $content;

in the xinetd script.

I guess that xinetd is supposed to push the output into the socket and add the terminating NULL byte. I don't know how xinetd works, but I've read that you just have to give your output into STDOUT when you're doing a xinetd service, so I guess this is the way to do it.

However what xinetd does after that is beyond me.

cgi::xml

XML(3pm)						User Contributed Perl Documentation						  XML(3pm)

NAME

       CGI::XML - Perl extension for converting CGI.pm variables to/from XML

SYNOPSIS

	 use CGI::XML;
	 $q = new CGI::XML;

	 # convert CGI.pm variables to XML
	 $xml = $q->toXML;
	 $xml = $q->toXML($root);

	 # convert XML to CGI.pm variables
	 $q->toCGI($xml);

DESCRIPTION

       The CGI::XML module converts CGI.pm variables to XML and vice versa.

       CGI::XML is a subclass of CGI.pm, so it reads the CGI variables just as CGI.pm would.

METHODS

       $q = new CGI::XML
	   creates a new instance of CGI::XML. You also have access to all of the methods in CGI.pm.

       $q->toXML([$root])
	   where $root is an optional parameter that specifies the root element. By default, toXML will not return a root element.

       $q->toCGI($xml)
	   where $xml is the XML you would like to convert to CGI.pm parameters. Values in the XML will overwrite any existing values if they
	   exist.

NOTE

       CGI::XML does not currently handle multiple selections passed from HTML forms. This will be added in a future release.
