The underlying purpose of the establishSecurityContext attribute is to determine whether a secure conversation is established between the client and the service before any application messages are exchanged. The secure conversation used in WCF is WS-SecureConversation. WS-SecureConversation is a Web service standard aimed at building a mechanism through which messages can be exchanged in a secure manner. It is based on the WS-Security standard to provide authentication of the message, and the underlying premise is that, although messagelevel authentication is fine for single or one-way messages, if the client and service wish to exchange multiple messages, a more efficient approach is required. Specifically, a security context could be established between the two parties. This context (called a Security Context Token, or SCT) could then be used to authenticate the messages. By default, the establishSecurityContext attribute is set to true. The basic assumption is that multiple messages will be sent along the WCF communications channel. The only reason to change the value is if you are sure the channel will be used only a single time, such as in the case of a one-time or one-way message. The establishSecurityContext attribute is valid only in the following bindings: wsHttpBinding wsHttpContextBinding ws2007HttpBinding
