Re: [ic] IPs that change with every access

I was looking at [env HTTP_COOKIE] at it looks like my MV_SESSION_ID

made by IP addresses that change with every access, usually just the
end portion of the IP address.  Most of these accesses are clearly
robots, but some of them are clearly not.  Is IC able to keep track of
a user's session properly when their IP changes with each access?

Ordinary users should not change their IP address with every request.
Spiders might do this, but they should be recognised by the Robot*
directives.

Users who use a proxy cluster might present themselves from a different
IP address every now and again.  Similarly, Also, if a user's ISP has a
weird DHCP setup then it might give the user a new IP address, rather
than renew the existing lease, but you shouldn't see that very often
in a normal browsing session.

Yet we see this all the time, primarily from users of AOL, who presumably all utilize a proxy cluster. That makes it a far more common occurrence indeed, at least here in the states ;)

That said, without changing the IC configuration, I have tested this situation by modifying the cookie in my browser, so that the IP address part no longer matches my actual IP address. As long as the session ID part is constant Interchange does not seem to mind, and the session behaves normally, all the way through checkout.
