Http class

HTTP GET
var request = new HttpGetRequest("http://www.server.com");
request.RequestGZIP = false; // default is true
request.Query.Add("name", "value"); 
request.Credentials = new NetworkCredential("username", "password");
// the url is now: "http://www.server.com?name=value"
Http.Get(request, OnRequestFinished);

The event handler method: 
private void OnRequestFinished(HttpResponse response)
{
	if (response.Successful)
	{
		// TODO: process response outside UI thread

		Deployment.Current.Dispatcher.BeginInvoke(() => {
			var text = response.Response;
			// TODO: set your data to view model or control 
			// (this code is called in the UI thread)
		});
	}
	else
	{
		if (!response.Canceled)
		{
			// display exception
			MessageBox.Show(response.Exception.Message);
		}
	}
}

HTTP POST
var request = new HttpPostRequest("http://www.server.com");
request.Data.Add("name", "value"); // POST data
request.Files.Add(new HttpPostFile("name", "file.jpg", "path/to/file.jpg")); // POST files
Http.Post(request, OnRequestFinished);

Exceptions
An exception is only thrown if there is a network or http problem. If HttpStatusCode != 200 the Exception property is set to a HttpStatusException instance or HttpStatusException is thrown in async operations.

Handle wrong HTTP status codes
try
{
    var result = await Http.PostAsync("url");
    Debug.WriteLine(result.Response);
}
catch (HttpStatusException e)
{
    // your status != 200 handler
    Debug.WriteLine(e.Result.HttpStatusCode);
    Debug.WriteLine(e.Result.Response);
}
catch (OperationCanceledException e)
{
    // TODO add your cancellation logic
}
catch (Exception e)
{
    // TODO add your exception handling logic
}


Http.Post("url", result =>
{
    if (result.Successful)
    {
        Debug.WriteLine(result.Response);
    }
    else if (!result.Canceled)
    {
        if (result.Exception is HttpStatusException)
        {
            var e = (HttpStatusException)result.Exception;

            // your status != 200 handler
            Debug.WriteLine(e.Result.HttpStatusCode);
            Debug.WriteLine(e.Result.Response);
        }
        else
            Debug.WriteLine(result.Exception.Message); // url not found, etc...
    }
});

Windows Phone

To prevent from popping up of error messages outside the page, call Http.AbortAllRequests(); in the method OnNavigatedFrom. This will abort all HTTP requests.

To prevent from popping up of error messages outside the page, call Http.AbortAll(this); (this is the current page) in the method OnNavigatedFrom. This will abort all HTTP request made on the current page.

WinRT / WinPRT (WP8)

Now with await/async support: 

try
{
	var response = await Http.GetAsync("http://www.domain.com");
}
catch (OperationCanceledException e)
{
	// TODO add your cancellation logic
}
catch (Exception e)
{
	// TODO add your exception handling logic
}

Classes

If the Http class is not built with USE_GZIP debug symbols only the Http* classes (see list below) are needed. The idea is to have a simpler standalone use of the http classes: If the classes are compiled outside the MyToolkit library the GZIP classes are no longer needed (found in "/Libraries" directory) and GZIP is no longer supported.
