proxy forwarding for IP address
The Blackbord website management system has a form function which includes the sender's IP address. However the web server almost always sits behind a web load balancer, so from the web servers standpoint that host submitting the form is always from the load balancer and not a real internet IP address. Load balancers often add a http header which contains the original requesters IP address. Can this http header data be included in form submissions to track down sender origins and form spammers?
