Behind a Firewall
How to get Updates if you are Behind a Firewall:

If you are behind a firewall and can only get to the outside by using a Proxy 
Server. We have code in the system for that.

Find out the name of your proxy server (name or number is ok), and the port it 
uses. Put those into this statement, execute it once, and save your image.

    HTTPSocket useProxyServerNamed: 'name of proxy server' port: 8080.

Anytime you want to, you may ask for updates. Or use any other http service in 
Squeak.

If you ever want to stop using the proxy server, just execute this.

    HTTPSocket stopUsingProxyServer.
