CometFilter getAuthType() returns null

[Sudeep Pradhan]

Hi,

I am using Tomcat 6.0.33. I have a CometProcessor Servlet and CometFilter. I 
use curl as http client and send username/password with basic authentication. 
The curl trace shows that the authentication type is basic. I have HTTPS in 
place. I try to get the AuthType and Principal in CometFilter but both are 
null.  I have the following code in place:

                                HttpServletRequest request = 
event.getHttpServletRequest();
                                HttpServletResponse response = 
event.getHttpServletResponse();

                                System.out.println("Auth Type : " + 
request.getAuthType());
                                System.out.println("User Principal: " + 
request.getUserPrincipal());

Can you tell me what needs to be done in order to get this working?

Thanks,
Sudeep
