Thanks for the reply. Actually at the end of my post I mention that I am currently using HTTPWebRequest, but the result is the same i.e. I only see the header info in the buffer received. So as a workaround I am using the UserAgent property and setting that value to the degrees I want my servo to turn to since I can see that property in the heading.
The code using WebRequest came directly from here:
In that example a long string value is put in a field called postData and sent to the web server. It is that string that I would like to Debug.Print on the Netduino 3 end.
I read through the post you referenced. I also downloaded the XivelyClient you mentioned, put it in a quick console app, and altered it to send to my Netduino 3. The result is also the same. All versions, WebRequest, HttpWebRequest, and XivelyClient's HttpWebRequest, successfully enter the Netduino 3 code listening for requests (ListenForRequest above) . I just don't seem to be able to tweeze out the data value I purposefully put in the byte array. The buffer received only prints:
POST / HTTP/1.1 Content-Type: application/x-www-form-urlencoded Host: 10.0.1.240 Content-Length: 3 Expect: 100-continue Connection: Keep-Alive
