How to passed a login page with java code

Hey,

I need to download a file from https URL.
The issue is that if I insert the URL to the iexplorer I redirect to the login page.

This url is accessible only after passing the login.

I want to be able to download this file with java code, but in order to do this I need to passed the login page. As I understand I need to have some kind of session here.
I need to do a login and than based on the response try to navigate to the desire URL.

Can any one give me an example or reference to article about it?

Thank you

Ps. I try Google, but I think I didn�t insert the right keywords.

So... you're trying to protect a resource from being downloaded until after the user has logged in?
Is this right?

No,

I am the client for this.

I need to write a client in Java that will download the file from this url, but the url is protect by user and password and you are redirect to the login page.

Oh, I see.

Do you actually have a valid username and password?

In any case, since you're writing client code, not servlets, this is not the correct forum for this question.
I'm moving it to our Sockets and Internet Protocols forum.

I'd say this is a case for the Jakarta HttpClient library, or -probably more convenient- the jWebUnit library. Both let you begin web sessions, let you run through the login page automatically, deal with session cookies (assuming that's how sessions are implemented), and let you access any URL that the web app provides.
