F5 config - X-Forward-Proto (XFP)

	# Recommended solution would be:
	# - Use Insert header, in the custom HTTP profile that you applied to the virtual servers.

	# For HTTPS Virtuals, insert: X-Forwarded-Proto, with a value of https
	# For HTTP Virtuals, insert: X-Forwarded-Proto, with a value of http

	# Of course you could also use apply an iRule to the Virtual Server, something like this should work:

	when HTTP_REQUEST {
	if { [SSL::mode] == 1 } {
