Question

I write an android application that send text data to asp.net webserver. I’m using next code to sent data via Http:

try {
    URL url = new URL(serverUrl);
    connection = (HttpURLConnection)url.openConnection();
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    // Enable POST method
    connection.setRequestMethod("POST");

    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "text/plain; charset=utf-8");
    output = new DataOutputStream(connection.getOutputStream());
    String finalUri = sendedUrl.replace("gaburl", "");
    output.writeChars(finalUri);
    //Toast.makeText(context, finalUri, 1000).show();
    output.flush();
    output.close();
}
catch(Exception e) {
    Toast.makeText(context, e.toString(), 5);
}

How I can receive and display data sending by output.writeChars(finalUri) method in ASP.NET application ? This process should executing like descripe bellow:

1)We have asp.net forms that are a target of sender’s android method desripe earlier;

2)Forms should read string data that sent to it and display it.

Help please
