Hi Beli,

Proxy chaining is a function of Proxy server (or ISA Server 2000). You may
sometimes see it referred to as upstream chaining. It simply means that if a
Proxy server can't service request from its cache, it will pass it to
upstream Proxy. As such, MSIE would simply pass a request to its proxy and
wait for reply.

There is, however, another feature with proxy servers (and ISA Server 2000)
if you use enterprise versions of mentioned software. It is called proxy (or
ISA Server) array. Rather then working serially, in this configuration proxy
servers work in parallel. Each proxy (ISA) is holding diferrent content in
its cache and serving this content to clients. Proxy (ISA) servers in an
array work together by using Cache Array Routing protocol (CARP). To find
out which servers form the array and to hit the proxy (ISA) server in the
array that most likely caches the requested content, the client (MSIE) is
loaded with array configuration. To do so web proxy client sends a request
in the form: array.dll?Get.Routing.Script.

As far as I remember MSIE 4.0 and above can work as web proxy clients as
described above.
