DiffServ settings are controlled through the HTTP DiffServ applet, shown in Figure 3.45,
which can be invoked by clicking the Specific DiffServ Preferences link.
Defining HTTP Compression Preferences
Another new feature introduced was the ability to compress HTTP packets that pass
through the ISA server. This helps to reduce the overall bandwidth required for web
surfing. The HTTP Compression settings can be configured by clicking on the Define
HTTP Compression Preferences link, which launches the dialog box shown in Figure 3.46.
Network clients specified under the Return Compressed Data tab will have their HTTP
responses compressed. In addition, the ISA server will request that web servers listed under
the Request Compressed Data tab compress their HTTP traffic. If there are no systems
listed under these tabs, compression does not occur.
Summary
The ISA Server Management Console is an extremely valuable, flexible tool that provides
for nearly all ISA functionality and configuration. Navigating the console tree and exploring
the various nodes available is an important part of understanding how ISA works, and
what tools are available for configuration of the server.
