// This example simulates this FORM:
// <form action="echoPost.asp" method="post">
// First name: <input type="text" name="firstName"><br />
// Last name: <input type="text" name="lastName"><br />
// <input type="submit" value="Submit">
// </form>
// The online FORM is found at this URL:
// https://www.chilkatsoft.com/simpleForm.html

// Build an HTTP POST Request:
req.HttpVerb = @"POST";

// The FORM target is http://www.chilkatsoft.com/processPost.asp
// An easy way of filling out most of the HTTP request object
// is to call SetFromUrl:
[req SetFromUrl: @"https://www.chilkatsoft.com/echoPost.asp"];

// Send form params using application/x-www-form-urlencoded
req.ContentType = @"application/x-www-form-urlencoded";

// The only remaining task is to add the params to the 
// HTTP request object:
[req AddParam: @"firstName" value: @"Matt"];
[req AddParam: @"lastName" value: @"Jones"];

// Send the HTTP POST and get the response.
// The POST is being sent to chilkatsoft.com, on port 443 (using TLS)
NSString *domain = @"chilkatsoft.com";
int port = 443;
BOOL tls = YES;

// The HTTP POST is sent here:
CkoHttpResponse *resp = [http SynchronousRequest: domain port: [NSNumber numberWithInt: port] ssl: tls req: req];
if (http.LastMethodSuccess == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// Display the HTML source of the page returned.
NSLog(@"%@",resp.BodyStr);
