  1. POWCF Routing to an SSL-enabled service
    text
    copied!<h1>Situation</h1> <p>I have modified the WCF Router sample to remove things that I'm not currently using, support clientVia rather than direct connections, and support HTTP and HTTPS. When I use the router as an intermediary to an MLS-enabled service, everything works fine. When I use the router as an intermediate to a TLS- and MLS-enabled service, I am failing on setting up the secure conversation.</p> <p>I am connecting to the router using HTTP and trying to route to the SSL-enabled service using HTTPS. If I try to use TLS to the router, then the router has to be on HTTPS.. and then I'd need the certificate to match, which is why I'm trying to setup the Client ==(HTTP)==> Router ==(HTTPS)==> Service relationship.</p> <p>The message sent to establish TLS in the case of a direct connection (which works) is very different from the message sent to establish TLS when going through the router. It looks like the client is dictating what's being sent, but shouldn't the client just be sending the MLS message and the router be establishing TLS and then sending the MLS message?</p> <p>Code and config info follow, and the resultant traffic (direct and through router) as well. Since no relevant changes have been made to the RouterBindingElement class, I've removed that from the code below (to save space).</p> <p>Any suggestions as to how to get the SSL working would be greatly appreciated.</p> <h1><strong>Code/Config</strong></h1> <h2><em>RouterBinding class</em></h2> <pre><code>public enum RouterTransport { Http = 0, Tcp = 1, NamedPipe = 2, Https = 3 } public enum MessageEncoding { Text, Binary, Mtom, } public class RouterBinding : Binding, IBindingRuntimePreferences { MessageEncoding messageEncoding;
