SPWF01SA HTTP POST problems

Hi, 

I'm trying to use the SPWF01SA module (IDW01M1 expansion board) like an HTTP server to send some POST response to an iPhone app. Now I'm able to open a TCP Server on the 80 port, shutting down the HTTPD server. But when I try to send even a simple HTTP GET with my browser or the app I can't see no data on the socket. The only thing that I can see is that the client joined the server but then the browser times out and left the connection.

Is there any way to setup the module to receive POST request and provide the correct POST response?

Is it possible to use or modify the internal HTTPD server?

I'm using the 160129-c5bf5ce-SPWF01S firmware
