    Question Proxy Authentication - Cannot login as multiple users

    Hello there,

    I have a class that open connections to URLs through a proxy. The proxy requires authentication, using NTLM protocol.

    I need to connect to one URL with a specific username and password, and then to another URL with another username/password combination.

    I tried using the class, but found out that there is no option to change the credentials when using it. Meaning that if I sent correct username and password, all the next connections will use these credentials, and ignore the other credentials I supply.

    Then I tried using the "Authorization" request property, like that:

    Java Code:
    String userPassword = username + ":" + password;
    String encoding = new sun.misc.BASE64Encoder().encode(userPassword.getBytes());
    urlConnection.setRequestProperty("Authorization", "Basic " + encoding);

    This also does not solve the problem. :(

    I test it like that: I send wrong credentials, and get 407 response code. Then I send correct credentials and get 200 response code. Then I send wrong credentials again, and I get 200.

    I follow redirections and I see that for every URL the proxy requests for username and password, so this is not a proxy problem.

    How can it be that the correct username and password are "remembered"?

    Default Solution

    The solution is to set the request property Proxy-Authorization and not Authorization...
