Do you call stat() or something equivalent?

I'm not sure what "appropriate response" means.  It depends
on which API you call.

Which server?  Your server?

I don't know how your server work.  Does it try to stat()
"/www.Google.com"?  If it does, it should get an error.
Actually, it should not prepend "/" in front if it!  It
should just try to stat() "www.Google.com" in the current
working directlry.
