Enabling ISA Server 2006 as a Web-Caching Server
FIGURE 8.7 Customizing HTTP caching settings.
Any number of cache rules can be configured, each with different settings. This allows for
the creation of granular cache options that can be set on a per-network or even percomputer
basis.
Configuring Proxy Web Chaining
ISA Server 2006 proxy servers, or even a third-party proxy product, can be chained
together inline so that proxy traffic is routed through both servers. This concept is known
as web chaining with ISA Server 2006, and it allows for the optimization of multiple proxy
servers by requiring users in different locations to use local ISA servers for proxy first, and
then to use a centralized one, for example.
To create a web-chaining rule, perform the following steps:
1. Open the ISA Server Management Console (Start, All Programs, Microsoft ISA Server,
ISA Server Management).
