I want to fetch a URL with java.net but any connection is refused. I know that when I ask for a page, my browser (IE) uses my Windows login ID to authenticate me, then pass my request through a proxy. Can someone please help me translate this process into the Java libraries and steps to fetch webpage? Thank you.

EDIT:
– I’m not sure what kind of authentication it uses here. Before any page is retrieved, it pops up a login window where I have to type in my domain\userid and password. How can I figure out the type of authentication?
– The proxy changes via an automatic configuration script.

    I recommend you use HttpClient, which makes authentication very simple:

    It’s not clear from your question what exactly the role of the proxy is here in authenticating you, but a combination of HttpClient + the right headers (if you need them) should be sufficient.
