Jota,
You need to use signed requests to make sure that your application
security is not compromised.
Let's say you have one user answer the poll, when the user submits the
answer the poll you send the answer and other info to your external servers
using makerequest (signed)
function request(url) {
var params = {poll_id : 23 ,
user_id : xxxxxxxxxxxxx,
answer_id : 4};
params[gadgets.io.RequestParameters.AUTHORIZATION] =
gadgets.io.AuthorizationType.SIGNED;
gadgets.io.makeRequest(url, response, params);
};
Please note, i'm providing the url to your external server as an argument to
your function.
On your server, you need to first validate the request to make sure that
it's not spoofed. Depending on your back end language, you'll have to use
the library that implement OAuth
and only carry the operations like inserting or consolidating data if the
requests are properly signed.

Once your are sure that the requests are genuine, you can perform your
processing , let's say like first (in php)
//Fetch the variables sent in the request body
$poll_id = $_REQUEST['poll_id'];
$user_id = $_REQUEST['user_id'];
$answer_id = $_REQUEST['answer_id'];
// Insert the values into the database
//Query the database for the same poll id
//return the response in JSON/HTML/Text format
You can in the same way, ask the results for a particular poll using
<os:HttpRequest> in opensocial templates.
