           Summary: New HttpSession created in HttpServletRequest under IPv6
           Product: Tomcat 5
           Version: 5.5.20
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Connector:Coyote
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Our JNLP clients use PostMethod.execute to send and receive data to a 
particular servlet.  Customers can launch the JNLP client from the home page.  
If the home page is launched via browser with 
http://<somehostname>:8080/homepage  or
http://<someip>:8080/homepage

Everything works fine. The problem is when tomcat is running on a host with an 
IPv6 tunnel

So if a JNLP client was launched from a home page that was brought up like:

http://[2002:8a2a:f915::1]:8080/homepage

Then a new HttpSession will exist in the HttpServletRequest.  Below is a simple 
servlet each time its invoked via the JNLP clients PostMethod.execute, a new 
session ID will be printed if the client was launched via IPv6 address.

import javax.servlet.*;
import javax.servlet.http.*;

{

    public void doPost( HttpServletRequest request,
                        HttpServletResponse response )
                            throws ServletException, IOException
    {
        System.out.println( request.getSession().getId() );
    }
}
