CkoHttpRequest *req = [[CkoHttpRequest alloc] init];

//  The PUT request to be sent will look like this:

//  PUT /request HTTP/1.1
//  Content-Type: application/jsonrequest
//  Cookie: JSESSIONID=1234
//  Content-Encoding: identity
//  Host: json.penzance.org
//  Accept: application/jsonrequest
//  Accept-Encoding:
//  Content-Length: 72
//  
//  {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

//  First, remove default header fields that would be automatically
//  sent.  (These headers are harmless, and shouldn't need to 
//  be suppressed, but just in case...)
http.AcceptCharset = @"";
http.UserAgent = @"";
http.AcceptLanguage = @"";

//  Suppress the Accept-Encoding header by disallowing 
//  a gzip response:
http.AllowGzip = NO;

//  If a Cookie needs to be added...
[http SetRequestHeader: @"Cookie" value: @"JSESSIONID=1234"];

//  Add the Content-Encoding: identity header.
[http SetRequestHeader: @"Content-Encoding" value: @"identity"];

//  Modify the default "Accept" header:
http.Accept = @"application/jsonrequest";

NSString *jsonText = @"{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}";

//  IMPORTANT: Make sure to change the URL, JSON text,
//  and other data items to your own values.  The URL used
//  in this example will not actually work.
