WCF

Hi I have been working on windows application that uses WCF service with protocol https.Now our client created a load balancing environment and hosted services in three server.Also he done the following steps for load balancer.

1.Installed SSL certificate on Load balancer instead of the servers.

2.So the communication between customer to load balancer is HTTPS and load balancer to server is HTTP.

3.Now services are using the configuration file(webconfig) which configured for https that worked on before load balancer.
