DJ, I had to install it on another domain where PHP isn't supported (and I hate Perl's get() (LWP::Simple)), and I personally think that IFrame is ugly, so I made the file
https://www.ubbdev.com/columns/lk/lt_js.txt (rename to .cgi).
Then I used [code][/code].
If you want to add it to your code, be my guest
Notes: 1. I think Content-type: text/javascript works better, but I didn't try it. 2. I didn't test it with $vars_config{NonCGIPath} and vars_config.cgi, I typed the full path.
