Stanley, I'm 100% sure this is either a bug in the java plugin/JDK, or there is some simple user error thing.
This is from bugzilla bug: http://bugzilla.mozilla.org/show_bug.cgi?id=79851
The problem is that the plugin forgets any Cookies sent from the server. I'm about to attach an applet that causes two complete HTTP request/response transactions to occurr. The first is a GET, the second is a POST. The respons from the GET request contains a Set-Cookie header, but the request of the POST does not contain this Set-Cookie header, thus any session information is lost.
Here's how I know what's going on.
I've modified my D:\Projects\ladybird\src\share\classes\sun\net\www\http\HttpClient.java like this:

You can see the Set-Cookie header coming back as a result of the first GET, but you don't see it going out on the following POST request.
What is to be done?
