Using LoadVars with PErl

Would anyone know any good sites that expain in more detail Perl scripts that can process variables sent by Flash MX.

My Perl script works with a “.load” and a “.send” but doesn’t work with a “.sendAndLoad” and if I use “.send” to send variables to write to a text file, the Perl script will output to a new browser window.

And, if anyone is a Perl/Flash programmer, will my script mess up writing to text files if more than one person attempts to do it at the same time?

Thanks in advance.
