access to password-protected web server

[igowi]

I want to access to the web server which requires username and password.
Let's say I get permission from the server.
After getting permission and getting another web page, I want to send user information. it's possible this just by creating another URL?
What I mean is....
class myClass
{
main()
{
URL url1 = new URL (..../a.cgi);
// getting permission
// getting input from the web server
URL url2 = new URL (.../b.cgi)
// Can I send form's values to this cgi since I got permission?
// I don't know how the authentication is valid.
}
}

thanks.
