Chilkat.Http http = new Chilkat.Http();

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    textBox1.Text += http.LastErrorText + "\r\n";
    return;
}

Chilkat.HttpRequest req = new Chilkat.HttpRequest();

//  Add the request params expected by the server-side:
req.AddParam("city","Paris");
req.AddParam("country","France");

//  Send the POST  (This is a real URL that may be tested.)
Chilkat.HttpResponse resp = null;
resp = http.PostUrlEncoded("http://www.chilkatsoft.com/httpTest/cityCountry.asp",req);
if (resp == null ) {
    textBox1.Text += http.LastErrorText + "\r\n";
    return;
}

//  The exact HTTP request sent and response received
//  by the example code above is as follows:
