[Jprogramming] How to use a proxy?

[bill lam]

I'm not sure why a firewall will dysfunction url resolution. However if you are 
banned from certain websites by your corporation or isp, a proxy server may be a 
solution.
0. google for a list of proxy server.
1. make a socket connection to a public proxy server, _not_ that local proxy 
server currently banning you.
2. pass the whole url, including the url's server name, in the get command. eg
   GET http://www.jsoftware.com/index.html
instead of
   GET /index.html
