(C# UWP/WinRT) Adding Cookies to an HTTP Request

Demonstrates how to add one or more cookies to an HTTP request. For Chilkat HTTP methods that use an HTTP request object, such as SynchronousRequest or PostUrlEncoded, cookies are added by calling the AddHeader method on the request object. For Chilkat HTTP methods that do not use an HTTP request object, such as QuickGetStr, cookies are added by calling AddQuickHeader.

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

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

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

// Build an HTTP POST request:
Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.SetFromUrl("http://www.chilkatsoft.com/echoPost.asp");
req.HttpVerb = "POST";

req.AddParam("param1","value1");
req.AddParam("param2","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","user=\"mary\"; city=\"Chicago\"");

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

Chilkat.HttpResponse resp = null;
string domain = "www.chilkatsoft.com";
int port = 80;
bool ssl = false;
resp = await http.SynchronousRequestAsync(domain,port,ssl,req);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// Display the HTML body of the response.
if (resp.StatusCode == 200) {
    // Show the last HTTP request header sent, which should include
    // our cookies...
    Debug.WriteLine(http.LastHeader);
}
else {
    Debug.WriteLine("HTTP Response Status = " + Convert.ToString(resp.StatusCode));
}

Debug.WriteLine("---------------------");

// 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","user=\"mary\"; city=\"Chicago\"");

string html = await http.QuickGetStrAsync("http://www.w3.org/");
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
}
else {
    // Show the last HTTP request header sent, which should include
    // our cookies...
    Debug.WriteLine(http.LastHeader);
