Send Cookies When Making WCF Service Calls


Introduction

This article presents an example on how to send cookies when making WCF service calls.

Background

Once in a while, you may find that you want to send some information in the form of "Cookies" to the server when making WCF calls. For example, if the WCF service is protected by a "Forms Authentication" mechanism, you will need to send the authentication cookie when making the WCF call to gain the required access to the service.
  • If you are calling a "REST" service using the "WebClient" class, this should not be a difficult task. You can simply work on the "CookieContainer" property of the "HttpWebRequest" class.
  • If you are calling a regular WCF service, and your client proxies are generated by the "Adding service reference" tool in the Visual Studio, the method to send cookies is not so obvious.
This article is to present an example on how to send cookies when making WCF calls using the Visual Studio generated client proxies.

The attached Visual Studio solution is developed in Visual Studio 2010. It has two projects:
  • The "WCFHost" is a simple ASP.NET MVC project that hosts the example WCF service.
  • The "WCFClient" is a simple WPF project. I will show you how to send cookies when calling WCF services in this project.
Let us start by first taking a look at the WCF service.

The WCF Service

The example WCF service is implemented in the "ServiceWithCookies.svc.cs" file in the "WCFHost" project.

Asynchronous Socket Programming in C#

Image
Objective The objective of this article is to demonstrate a socket-based client/server application that will allow two-way asynchronous communication between a server and multiple client applications. Because this example uses asynchronous methods, the server application does not use threads to communicate to multiple clients (although internally the asynchronous communication mechanism uses threads at the OS level). The Difference Between Synchronous and Asynchronous Communication in Network Programming The key difference between synchronous and asynchronous communication can be explained with an example. Consider a server application that is listening on a specific port to get data from clients. In synchronous receiving, while the server is waiting to receive data from a client, if the stream is empty the main thread will block until the request for data is satisfied. Hence, the server cannot do anything else until it receives data from the client. If another clien
