Signed japplet doesn't pass cookie sessionid correctly in NS6

Question

I have a signed applet that gets the sessionid and fileid from the calling page and does a get
to a servlet and the servlet looks up the fileid and sends back the binary file to the applet.
In IE5.5, it works fine. But in NS6, the sessionid doesn't get sent the same way and hence the servlet thinks the session is bad. I printed out all the cookies on the servlet plus some request.functioncalls and this is what it looks like on NS6. This is iplanet app svr. Notice the gx_session_id_ cookie is entered twice with NS6 but not in IE5.5. The session not found error is when the servlet tries to validate session. If it has a good session, it prints out the userid and orgid.
/// NS 6 log entries
Cookie: GX_jst = 5a6e7156662d6164
Cookie: GX_sst =
Cookie: ias_has_been_authenticated =
Cookie: gx_session_id_ = 843c7ef36d77ec93, gx_session_id_=843c7ef36d77ec93
Cookie: NSES40Session = 843c7ef36d77ec93
Error: session not found
DownloadServlet: SessionId from URL? false
DownloadServlet: SessionId from Cookie? false
DownloadServlet: Is requested SessionId valid? false
DownloadServlet: Requested SessionId is null
//In IE5.5, the cookies and session function calls are good:
Cookie: GX_jst = 5a6e7156662d6164
Cookie: GX_sst =
Cookie: gx_session_id_ = ddc742356b281b62
Cookie: ias_has_been_authenticated =
userID: 572
orgID: 1006
DownloadServlet: SessionId from URL? false
DownloadServlet: SessionId from Cookie? true
DownloadServlet: Is requested SessionId valid? true
DownloadServlet: Requested SessionId is ddc742356

Here is the servlet code the logs these entries:
// dump cookies
Cookie[] cookies = req.getCookies();
for (int i=0; i<cookies.length; i++)
log("Cookie: " + cookies.getName() + " = " + cookies[i].getValue() );
//Determine if session is valid and if valid extract information from session.
session = validateSession(req, res);
if (VERBOSE) {
log("SessionId from URL? " + req.isRequestedSessionIdFromURL());
log("SessionId from Cookie? " + req.isRequestedSessionIdFromCookie());
log("Is requested SessionId valid? " + req.isRequestedSessionIdValid());
log("Requested SessionId is " + req.getRequestedSessionId());

Answer 1

I found the problem, earlier the applet coder added a setRequestProperty('Cookie', sessionstring) and we thought that got IE to work. I just took it out and the sessionid is being passed automatically. Both browsers work now.
