As I’ve covered this subject using WSE3, now to look at adding an SSO token to a WCF header.<\/p>\n
Configuration<\/strong><\/p>\n In your App.config you’ve probably got something like<\/p>\n We’re going to add two more configuration files, as follows<\/p>\n As the names suggest, these file will include the config for behaviors and extensions.<\/p>\n Let’s take a look at the servicemodel-behaviors-config.xml first<\/p>\n Now we need to actually define what implements ssoEndpointBehaviorExtension<\/em>. So in the servicemodel-extensions-config.xml configuration, we might have something like the following<\/p>\n So as we can see, the ssoEndpointBehaviorExtension<\/em> behavior is associated with the SsoService assembly and the type SsoEndpointBehaviorExtensionElement.<\/p>\n Implementing the behavior\/extension<\/strong><\/p>\n Unlike WSE3 we do not need to use an attribute to associate the extension with a service call.<\/p>\n Let’s start by looking at the SsoEndpointBehaviorExtensionElement behavior extension.<\/p>\n The code above relates to the actual extension element, so really just creates the actual behavior when required. Here’s the SsoEndpointBehavior.<\/p>\n This code simply adds the inspector to the message inspector. Finally let’s look at the code that actual intercepts the send requests to add the SSO token to the header.<\/p>\n In the above code, we create an addition to the message header, with the name “ssoToken” followed by any namespace and then the value we wish to store with the header item. In this case our SSO token.<\/p>\n","protected":false},"excerpt":{"rendered":" As I’ve covered this subject using WSE3, now to look at adding an SSO token to a WCF header.
