Exposure of client IP addresses in net/http

— Microsoft

When httputil.ReverseProxy.ServeHTTP was called with a Request.Header map containing a nil value for the X-Forwarded-For header, ReverseProxy would set the client IP as the value of the X-Forwarded-For header, contrary to its documentation. In the more usual case where a Director function set the X-Forwarded-For header value to nil, ReverseProxy would leave the header unmodified as expected.
