BOOL success = NO;

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

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

// The XML sent in the body of the request is application
// specified -- it should contain whatever the server-side
// application is expecting..
NSString *xmlStr = @"<?xml version=\"1.0\" encoding=\"UTF-8\"?><appXml><something>123</something></appXml>";

NSString *urlEndpoint = @"http://www.chilkatsoft.com/xmlEcho.asp";
NSString *xmlCharset = @"utf-8";

CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpStr: @"POST" url: urlEndpoint bodyStr: xmlStr charset: xmlCharset contentType: @"application/xml" response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// The raw HTTP request sent by the above call is:

// POST /xmlEcho.asp HTTP/1.1
// Content-Type: text/xml
// Host: www.chilkatsoft.com
// Accept: */*
// Accept-Charset: ISO-8859-1,utf-8;q=0.7,*; q=0.7
// Accept-Language: en-us,en;q=0.5
// Accept-Encoding: gzip
// Content-Length: 81
// 
// <?xml version="1.0" encoding="UTF-8"?><appXml><something>123</something></appXml>

// Examine the Body of the HTTP response
// This would be the XML response sent by the server.
NSLog(@"%@",resp.BodyStr);
