I wrote a java program to get a content of a URL given. It is working fine for
internal URLs. But if i try to access some web pages benind my proxy server
(say http://www.yahoo.com) it is not working. So i set http.proxyHost and
http.proxyPort properties of jvm. Now it is throwing "407 proxy authorization
error". It is due to my proxy needs a username and password. I do not how to
pass proxy user name and password. Can some body help me out to solve this
problem.
