Figure 7-5:Hierarchical approach to pattern rules

In Figure 7-5, the pattern rules direct user requests as follows:

•www.buystuff.com/ebooks/authorsa/* are directed to server group 1

•www.buystuff.com/ebooks/authorsb/* are directed to server group 2

•www.buystuff.com/ebooks/authorsc/* are directed to server group 3

and so on.

This hierarchical approach has most of the advantages of the first approach, and is also well-suited to unindexed, browsable, static content. All of the content can be browsed using a simple CGI or ASP script that inspects the file system and creates links, as appropriate.

The following commands show the configuration for ebooks, using the hierarchal method.

config service vip 10.65.31.201 port 8080 proto tcp l7 class http
