WCF Service (wsHttpBinding binding) behind F5 load balancer

wcf https f5
svg_stack picture svg_stack · Nov 9, 2010 · Viewed 7.6k times · Source

current setup: - i have got a WCF service with wsHttpBding, see the service config below - i have implemented a ServiceHostFactory to solve the problem of incorrect schema location and soap addresses, modifying them from machine name to the correct server hostname - my test client (WCFStorm) i can generate a proxy, see all the methods and invoke them successfully. - my dev environment (client-> HTTPS -> service) works perfectly.

problems: - prod environment (client -> HTTPS -> F5 -> HTTP -> service) - my service is behind F5 load balancer which offloads SSL - my test client (WCFStorm) i can generate a proxy and see all the methods but when i invoke any of the methods i get a remote server not found 404 error

  • my service config: <services> <service behaviorConfiguration="Service1Behavior" name="MyService"> <endpoint name="secure" address="" binding="wsHttpBinding" bindingConfiguration="custBinding" contract="IService"/> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" /> </service> </services> <bindings> <wsHttpBinding> <binding name="custBinding"> <security mode="Transport"> <transport clientCredentialType="None" /> <message clientCredentialType="None" negotiateServiceCredential="false" establishSecurityContext="false" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="Service1Behavior"> <serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" httpGetUrl="http://myserver/MyService.svc"/> <serviceDebug includeExceptionDetailInFaults="true"/> <dataContractSerializer maxItemsInObjectGraph="6553600" /> </behavior> </serviceBehaviors> </behaviors>

  • please note that all my schema locations and soap addresses on the wsdl are correct in prod, but i simply cannot invoke any methods.

please help.

We have a similar situation and here's how we got it working.

in the service - we changed the binding to use basicHttpBinding and added a key that must be passed with every request.

in the client - we changed the http in the config to https and in the basicHttpBindings config changed the security mode to Transport with clientCredentialType="None".

Hope this helps.

UPDATE: I found this article soon after and I updated the configuration and it worked. So now we are using wsHttpBinding instead of basicHttpBinding. http://blogs.msdn.com/b/morgan/archive/2010/04/15/setting-up-wcf-with-a-load-balancer-using-ssl-in-the-middle.aspx
