IP authentication failure

[Thomas Edelblute]

It appears that our Internet Service Provider implemented a new server
this week that allows for Web caching.  The unfortunate result is that
is acts as a proxy server, placing its IP address in place of the IP
address our library machines are sending out.  This results in
authentication failures to sites that use IP authentication.  Newsbank
is working on a fix for us where we can use a user name and password to
download a cookie to our computers.  I will try this cookie
authentication out tomorrow morning.

Has anybody else run across this with their ISPs?  Our ISP says that
using a Web cache is something more and more ISPs are doing to increase
the speed of Web access.  If they are right, what other problems might
we run into with Web caching?
