// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoHttp *http = [[CkoHttp alloc] init];

// The Cookie header field has this format:
// Cookie: name1=value1 [; name2=value2] ...

// Build an HTTP POST request:
CkoHttpRequest *req = [[CkoHttpRequest alloc] init];
[req SetFromUrl: @"http://www.chilkatsoft.com/echoPost.asp"];
req.HttpVerb = @"POST";

[req AddParam: @"param1" value: @"value1"];
[req AddParam: @"param2" value: @"value2"];

// To add cookies to any HTTP request sent by a Chilkat HTTP method
// that uses an HTTP request object, add the cookies to the
// request object by calling AddHeader.  

// Add two cookies:
[req AddHeader: @"Cookie" value: @"user=\"mary\"; city=\"Chicago\""];

// Send the HTTP POST.  
// (The cookies are sent as part of the HTTP header.)

CkoHttpResponse *resp = 0;
NSString *domain = @"www.chilkatsoft.com";
int port = 80;
BOOL ssl = NO;
resp = [http SynchronousRequest: domain port: [NSNumber numberWithInt: port] ssl: ssl req: req];
if (http.LastMethodSuccess != YES) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// Display the HTML body of the response.
if ([resp.StatusCode intValue] == 200) {
    // Show the last HTTP request header sent, which should include
    // our cookies...
    NSLog(@"%@",http.LastHeader);
}
else {
    NSLog(@"%@%d",@"HTTP Response Status = ",[resp.StatusCode intValue]);
}

NSLog(@"%@",@"---------------------");

// Some Chilkat HTTP methods do not use an HTTP request object. 
// For these methods, such as for QuickGetStr, cookies (or any HTTP request header) 
// are added by calling SetRequestHeader.  
[http SetRequestHeader: @"Cookie" value: @"user=\"mary\"; city=\"Chicago\""];

NSString *html = [http QuickGetStr: @"http://www.w3.org/"];
if (http.LastMethodSuccess != YES) {
    NSLog(@"%@",http.LastErrorText);
}
else {
    // Show the last HTTP request header sent, which should include
    // our cookies...
    NSLog(@"%@",http.LastHeader);
