Subject: WCF 3.5 RemoteEndpointMessageProperty in load balancing situation
Print | Individual message | Show original | Report this message | Find messages by this author
I have a WCF service in .Net 3.5 and I am trying to use
RemoteEndpointMessageProperty to get the IP address of the client who
consume the service, for trouble shooting purposes:

OperationContext context = OperationContext.Current;
MessageProperties properties = context.IncomingMessageProperties;
RemoteEndpointMessageProperty endpoint =
properties[RemoteEndpointMessageProperty.Name] as
RemoteEndpointMessageProperty;
if (endpoint != null)
{
    IP = string.Concat(endpoint.Address, ":", endpoint.Port);

}

However, since the WCF service is hosted in IIS behind a load balancer, the
IP address I got is always the IP of the load balancer.
Is there any way to get around this so that I can get the true IP of the
client?

Thanks
