Just a quick one here.....

How likely is it that UK AOL users are directed through a US AOL webcache server? Could this happen?

Thanks in advance.

Pretty unlikely as the phone number given is a uk one and so would use a designated uk server

As it's AOHell, it wouldn't suprise me if it did.

Depends how their infrastructure works...

And copy&paste what is in the "HTTP_X_FORWARDED_FOR &
HTTP_VIA " lines. If you're cached it should be easy enough to work out where the IP addresses sit.

it would surprise me if even AOL would send you across (expensive) transatlantic bandwidth twice.

no..... its not me. I'm trying to work something out @ work.

More a theory, really.

e.g.

Dial-Up Freeserve gives..

REMOTE_ADDR 195.92.67.70
HTTP_X_FORWARDED_FOR 81.78.102.205
HTTP_VIA 1.1 webcacheH06 (NetCache NetApp/5.2.1R3)


Cache is 195.92.67.70. which a few traceroutes indicates is certainly very near Freeserves's backbone and is certainly this side of the atlantic - but Freeserve's dns names aren't very informative...

(and before anyone squeals - no I dont care if I expose a transient dial-up IP address that has already chganged)

That's a handy URL

Especially if you deploy Internet Gateways for large private networks with several resilient NAT firewalls and web-cache hierarchies and you want to check which path you're using

Plus it lets me keep my WebCache software in-line with freeserve who I figure have time to do more testing than me
