SYMPTOMS

Consider the following scenario:
  • You use Network Load Balancer (NLB) to route messages for a set of computers that host Windows Communication Foundation (WCF) services. These services use secure sessions by setting the authenticationMode attribute to "SecureConversation."
  • You try to add Webheaders to messages in the application layer. After you do this, the NLB can use the Webheaders to route messages.
In this scenario, you cannot add WebHeaders to messages that are used to negotiate the session. Therefore, the two types of messages are routed to different host computers. In this situation, any cached session data in the host computer is unavailable and the WCF services fail.
