> Thank you for that info Phillipe. That is exactly what I needed. I realized
that I would probably need to perform a GET somewhere, this tells me exactly
how to figure out what it is I need to send back in my GET request. Because
it is the plugin that retrieves the initial response it doesn't work as
automagically as the browser which is why nothing happens after my initial
POST.
