Sending response back from http handlers

In this post, I will explain about sending a response back from http handler to the calling page. The page that invoked http handler can be either .NET or Java.

I am sending response back in json format.

In the following method, AuthResponse is my custom class. You can use you own class there.

/// <summary>
/// This method sends the response in json format
/// </summary>
/// <param name=”context”></param>
/// <param name=”authResponse”></param>
private void SendResponseInJson(HttpContext context, AuthResponse authResponse)
context.Response.ContentType = “application/json”;
context.Response.ContentEncoding = Encoding.UTF8;

System.Web.Script.Serialization.JavaScriptSerializer jsSerializer =
new System.Web.Script.Serialization.JavaScriptSerializer();
string jResponse = jsSerializer.Serialize(authResponse);


Read the response from http handler in an ASP.NET page,

HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
Stream stream = myResponse.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string result = reader.ReadToEnd();

The result string will contain the actual text that was sent from the http handler.

This can be useful when you want to send and receive data between two different web applications.
