Hi
Rose. That is not a problem with your code, but with the configuration of your computer.
If you are on windows, you can check in your computer has a localhost entry in its host file.
(on my xp installation, the host file is located at C:\WINDOWS\system32\drivers\etc)
The entry should look like this:
If the entry is there, or if adding the entry does not resolve your problem, you can contact your support team to help resolve it.
Executing
> tracert localhost (traceroute on linux and unix)
and
> ping localhost
will give your support team useful info.
