Don't redirect to request uri If a url is requested which isn't the FLYS start page (FLYS.html) the user had been redirected to this page after successfull authentication. This caused wrong redirects after a authentication is expired and if the browser preloads e.g. the CSS file. Therefore allow to set a redirect url in the web.xml config to always redirect the user to the correct page after successfull authentication. Fix for flys/issue970 (Zugangsfehler FLYS 2.9.3)

package de.intevation.flys.client.server.auth;

import java.io.IOException;

import de.intevation.flys.client.server.features.Features;

public interface Authenticator {

    public Authentication auth(String username, String password, String encoding, Features features)
        throws AuthenticationException, IOException;

}
