Yes, unfortunately, same thing and the hosts file is also correct.

This is in OS X, and the valida†or URL I'm calling is being served by  
Apache 2.2, and is a ScriptAlias like so (in an includ of httpd.conf):

ScriptAlias      /w3c-validator/check   '/Applications/Validator- 
SAC.app/Contents/Resources/validator/httpd/cgi-bin/check_wrapper.sh'

Thing that's got me baffled is that I can go to it just fine in a  
browser, I can `curl` it, but, now, after a little more digging, wget  
can't get it either!

So:
curl  http://localhost/w3c-validator/check			   <-- returns HTML code
any browser to  http://localhost/w3c-validator/check  <-- returns HTML  
code
t.w.c.getPage("http://localhost/w3c-validator/check") <-- 404
wget  http://localhost/w3c-validator/check		   <-- 404

So what the heck is the difference in how these things resolve that  
address!?

Thanks,
