Depends on your DNS. Works for some without.

The dns works. But the browser doesn't. Without the trailing dot the browser looks up the .com address.

With the dot it works, but then the browser fixes up the url, and removes the dot - so all subsequent requests don't work.

(This is for me, using firefox on linux.)

Fine in Opera.

seems safari users are struggling without the . as well .. probably a webkit issue then

edited for spelling mistake

Works fine here with Google Chrome.
