Comment (by ruckus):

 When a request is proxied, the IP addresses are collected in the HTTP
 header X-Forwarded-For.  That is a comma separated list.

 The REMOTE_ADDR comes from the web server and records the address (IP or
 other protocol) of the remote end of the connection to the server.  It is
 always a single address.  Its definition comes from the CGI environment
 spec: http://hoohoo.ncsa.uiuc.edu/cgi/env.html

 Can you show an example of web server software or other circumstances when
 REMOTE_ADDR has a comma separated list of addresses?
