I am wondering if there is any way to read the post values of the Ethernet Shield's server. I am able to successfully use GET variables from the browser directly to the server, but I can not get the value of POST variables from a different server to the Ethernet Shield server. Does anyone know if this is possible and if so, how?
i wish i knew im looking for the same answer
Ok, so I have been told that providing a little bit of code might help the situation here.
HTML Form (stored on separate Ubuntu server, not Arduino)
Line 26-29 is the form that submits a POST of "0=1",
Arduino Code:
Line 79 starts the function that is supposed to read POST and GET values.

Issue:
POST / HTTP/1.1 Host: 192.168.1.202 Connection: keep-alive Content-Length: 3 Cache-Control: max-age=0 Origin: http://localhost User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1 Content-Type: application/x-www-form-urlencoded Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Referer: http://localhost/Arduino-Home-Automation/index.php Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

You can clearly see that Content-Length is 3, this changes with the length of the form POST, so if POST was 11=1 then Content-Length would be 4.
Now when I user the url such as 192.168.1.202/?0=1 I am presented with:
GET /?0=1 HTTP/1.1 Host: 192.168.1.202 Connection: keep-alive User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 0
?48
Clearly you can see that the get value is easily readable from the output above. Any ideas why POST does not work like this?
