X-Forwarded-For

Hi,

It may be a stupid question, but perhaps somebody could tell me what is
the format of the X-Forwarded-For header that Squid sets. I understand
this:

X-Forwarded-For: 194.108.132.67

but what does it mean when there're more of IP's listed, like in the FAQ
(http://squid.nlanr.net/Squid/FAQ/FAQ-4.html#ss4.15)?:

X-Forwarded-For: 128.138.243.150, unknown, 192.52.106.30

Thanks,

Jan S.
