I cannot visit http://localhost:8080/ and get a webpage...

The connection was refused when attempting to contact localhost:8080.

Now, telnet localhost 8080 works just fine... but the resulting page is broken with the 3.01 stable release I just downloaded:

<!-- ~/tmp tbrannon --> telnet localhost 8080
Trying ::1...
Connected to localhost.

description changed.

status changed from new to closed.
resolution set to fixed.

Fixed in [1636] (trunk and 3.0 branch). HTTP/1.1 requires a Host header, but HTTP/1.0 (which you're sending) does not. The code in _cprequest erroneously used dict.__getitem__ instead of dict.get.
