                                 javax.servlet.ServletResponse response)

getHost

protected java.lang.String getHost(javax.servlet.ServletRequest request)

Returns the host name or IP associated with the current subject. This method is primarily provided for use during construction of an AuthenticationToken.

The default implementation merely returns ServletRequest.getRemoteHost().

Parameters:

request - the incoming ServletRequest

Returns:

the InetAddress to associate with the login attempt.

isRememberMe

protected boolean isRememberMe(javax.servlet.ServletRequest request)

Returns true if "rememberMe" should be enabled for the login attempt associated with the current request, false otherwise.

This implementation always returns false and is provided as a template hook to subclasses that support rememberMe logins and wish to determine rememberMe in a custom mannner based on the current request.

Parameters:

request - the incoming ServletRequest

Returns:

true if "rememberMe" should be enabled for the login attempt associated with the current request, false otherwise.
