Matt and Luke,

Thank you, you are both of course right, I could not tell from the code.

What Patrick says is very true; I produce most of my pages through Perl 
programmes and have (in the past) used any number of "non-standard" 
suffixes; for instance, if we had the domain foobar.com, I would have 
the starting page as foobar.com which would have a URI of 
http://foobar.com/foobar.com - sad really ;-)  With the Apache Web 
server, provided that you define .com (or .wu) as being a Perl (or 
whatever) file:
AddHandler cgi-script .com	[or .wu]
...and you set the DirectoryIndex to be foobar.com, this is what will be

picked up by default.

When it comes to CGI programmes (not in the DocumentRoot directory), you

can have whatever extension you like since they are completely ignored -

at least in a Unix-ish environment.  [It's up to the programme to send 
the correct MIME type rather than trying to work it out from the file 
extension.]  You could even have a Perl programme tagged as .php, .cf or


Conclusion: You can't be 100% sure about what is producing a Web page 
from the file extension.  If you're concerned with accessibility, you 
should be looking at the CONTENT rather than the means by which it is
