Content-aware cache switching

Basic example of content-aware cache switching
The diagram in Figure 21 illustrates a configuration that uses content-aware cache switching to
cache GIF files on one set of cache servers and different kinds of files on another set.
In this configuration, Cache Group 1 consists of three cache servers. CacheServer1 and
CacheServer2 are allocated to Server Group ID = 1, and CacheServer3 is allocated to Server Group
ID = 2. The ServerIron ADX has CSW policies in place that cause HTTP requests to be directed to
the cache servers as follows:
• HTTP requests containing URL strings that end with the text "gif" are sent to one of the cache
servers in Server Group ID = 1.
• If a URL string does not end with the text "gif", the HTTP request is sent to the cache server in
Server Group ID = 2.
