title: Get client IP address in self-hosted SignalR hub
body: <p>How do you go about getting the IP address of the remote client in a self-hosted SignalR hub? According to <a href="https://stackoverflow.com/questions/11044361/signalr-get-caller-ip-address">this question</a>, you could at one point get it using Context.ServerVariables[], but that seems to be missing from the latest version of SignalR.</p>
