1) HTTP Post Request (from a windows form application)

2) Retrieve data for HTTP Post Request (from a ASPX Web Application)

// get HTTP post data
Stream dataStream = Request.InputStream;
StreamReader reader = new StreamReader(dataStream);
string strTemp = "";
string strResult = "";
while ((strTemp = reader.ReadLine()) != null)
{
strResult = strResult + strTemp;
}
dataStream.Close();

// response for testing purpose

}
private static void LogToFile(string strURL,
string strMess)
{
DateTime Now = System.DateTime.Now;
string strLog = "";
string strNow = Now.ToString("yyyyMMdd");
string REQUEST_LOG = strURL + "XXX" + strNow + ".txt";

}
