Enabling CGI Script from Apache's htdocs directory

[monkfan]

Fellow monks,
I have a very simple cgi script like this:

#!/usr/bin/perl

print "Content-type: text/html\n\n";
print "Hello World !! It works.\n";

which I stored in:

/usr/local/apache/htdocs/Test/cgi-bin

However I was unable to see it working from this website:

http://bioinfo-z.comp.nus.edu.sg/Test/cgi-bin/hello.cgi

However, my index.html can be accessed without problem here.

What was wrong with my setting above? Was there any special structure required for CGI?
As a SU I've also activated my Apache's

 svcadm enable www:apache22
