Thanks everyone very nice tips and links. Salk31& Cokol, you were right, I didn't need the "?", PHP page wouldn't get the first parameter because of the "?"
VM, nice article and very smart hack... but it got me wondering whether I will be able to maintain status on the server (using sessions), especially after I read the other hack on how to use the iframe name to store information. I am lucky that I am controlling both the PHP pages and GWT application, and both will be running from the same domain and server, so I tried deploying both on the same server and they communicate perfectly with no hassle using RequestBuilder. These issues are raised when I try to run the GWT application through Eclipse. I could be wrong, but it seems like no matter what technique you use to send a cross server POST request, will give you a lot of pain especially if you are interested in maintaining status... Thanks a bunch.
