The Apache Server Application Programming Interface is a set of separate web services. You must manage context and state in your clients that make requests to the web services. If you do not share context and state across your web services clients you will encounter authentication exceptions because the web services cannot tell that you intend for your requests to be in the same user context. One way to share state and context among your Server Application Programming Server clients, if you are using a .NET Framework client, is to use the WCF Cookie Manager.
