Chilkat.HttpRequest req = new Chilkat.HttpRequest();

//  Loads the HTTP request object from a URL
req.SetFromUrl("https://www.youtube.com/watch?v=fAZdTchQePc&t=45s");

//  The verb will be "GET"
Console.WriteLine("verb = " + req.HttpVerb);
//  The path will be "/watch"
Console.WriteLine("path = " + req.Path);

//  The output of this loop will be
//  0) v: fAZdTchQePc
//  1) t: 45s
int i;
int numParams = req.NumParams;
for (i = 0; i <= numParams - 1; i++) {
    Console.WriteLine(Convert.ToString(i) + ") " + req.GetParamName(i) + ": " + req.GetParamValue(i));
}

//  View the request that would be sent if SynchronousRequest is called.
//  The HTTP request will be a GET that looks like this:
// 
//      GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
//      Host: domain
// 
//  Note: The HOST header will automatically get filled in with the actual domain when SynchronousRequest is called.

Console.WriteLine(req.GenerateRequestText());

//  We can add additional params
req.AddParam("artist","Richard Bona");
req.AddParam("musicType","Jazz");
req.AddParam("festival","Estival Jazz Lugano");
req.AddParam("year","2008");

//  Now examine the request that would be sent
// 
//      GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1
//      Host: domain
// 
Console.WriteLine(req.GenerateRequestText());

//  We can remove a parameter:
req.RemoveParam("t");
Console.WriteLine(req.GenerateRequestText());

//  What happens if we change the request from a GET to a POST?
req.HttpVerb = "POST";
//  The request will now look like this:
// 
//     POST /watch HTTP/1.1
//     Host: domain
//     Content-Length: 93
// 
//     v=fAZdTchQePc&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008
// 
Console.WriteLine(req.GenerateRequestText());

//  What happens if we make it a multipart/form-data?
req.ContentType = "multipart/form-data";
//  Now the POST looks like this:
// 
//     POST /watch HTTP/1.1
//     Content-Type: multipart/form-data; boundary=------------020906020106050705030807
//     Host: domain
//     Content-Length: 545

//     --------------020906020106050705030807
