proxy - What is the difference between X-Forwarded-For and X-Forwarded-IP?

Question

To obtain the client IP address in my ASP.NET application I've used the X-Forwarded-For, and get the first IP address from the list (accordingly to the information I've found, there is a client, proxy1, proxy2..). But I've heard recently that it is better to get this information from X-Forwarded-IP header because the client IP address in X-Forwarded-For can be modified by proxy, what is the difference, and which one address should I use?

Answer 1

X-Forwarded-For is the conventional way of identifying the originating IP address of the user connecting to the web server coming from either a HTTP proxy, load balancer.

X-Forwarded-IP is the conventional way of identifying the originating IP address of the user connecting to the email server through an HTTP mail service.
