Yes, but can we be sure that subsequent proxies/lbs will always append to the final header in the list? I don't have Squid or anything else installed, so am not sure of it, but am going on assumption that they probably just grab the first XFF that they find. Any confirmation (or rejection) of this behaviour would be appreciated. Thanks, Eric -- To unsubscribe send an email with subject unsubscribe to po...@apsis.ch.
