Content-aware cache switching
2
In the configuration in Figure 22 on page 85, the ServerIron ADX has CSW policies in place that
cause HTTP requests to be directed to the cache servers as follows:
• Requests that have URL strings with the text "asp" anywhere within go directly to the Internet.
• Requests for all other content are directed to one of the cache servers in server group ID =
100.
• HTTP 1.0 requests that have a pragma:no-cache header are sent to the Internet regardless of
the URL string.
• HTTP 1.1 requests that have a Cache-Control header containing a no-cache directive are sent
to the Internet regardless of the URL string.
