how to download a file using httpunit in Java

Hello,
I'm using httpUnit to automate some manual actions.

I have to connect to my server(SSL with cookies) fill a username password, then submit and then there is file to download but I don't have to enter or press anything, after the submit button the server redirect me to the file to download.

I manage to go on the link and fill the form with username and password and submitting but I don't know which methods to use to download to file.
Also, even I don't have any errors, I don't know if the submit is well done, May I use the httpunit.cookies or something as is is https ?

Thanks
