What's going on is this: whenever you use a host name in a URL, it needs to be
looked up in a "Domain Name Service". Most ISPs have you configure your dial-up
networking connection to use the ISP's name server for this, which of course
only works when you are online.
Once the name "localhost" is looked up and turned into its IP address equivalent
(127.0.0.1), you can disconnect and continue working, because your PC remembers
this translation -- well, at least until you reboot.
To make it work without having to connect, you can try one of the following
approaches:
* Connect with the IP address instead:
http://127.0.0.1:8080/my/servlet
* Add the following line to c:\Windows\HOSTS (on Unix systems, /etc/hosts)
127.0.0.1 localhost
Your computer's TCP/IP stack should look here first, so it will know how to
translate "localhost" without having to be online.
