[REBOL] Script in Secure domain

[tim]

I have a rebol CGI script running in the unsecured
part of my domain at 
http://johnsons-web.com/cgi-bin/hello-world.r
if I attempt to access the same script from
https://johnsons-web.com/cgi-bin/hello-world.r
secure domain, I get an error message from the browser.

I also have a perl script running on both domains

http://johnsons-web.com/cgi-bin/hello-world.cgi
https://johnsons-web.com/cgi-bin/hello-world.cgi

and it works on both sides.

Here's the first line of the rebol script:
#!/usr/bin/rebol -cs

Does any one know what I could be doing wrong here?

Thanks
Tim
