Creating Domain and URL Switching Rules

To simplify the creation of pattern rules, you can use wildcard combinations. The 
allowable wildcards are described in Table 7-1.

Every layer 7 rule needs a default domain, which can contain only a default 
pattern-rule. This rule is used to decide where to forward traffic in the event that none 
of the configured rules match.

You can use a wildcard for the domain when the format of the domain is unknown or 
unimportant. For example, the following configuration is for HTTP services with an 
unknown domain format:

config service vip 10.65.101.20 port 80 protocol tcp l7 class http

config domain name *

config pattern-rule default server-group-name sg2

Table 7-1: Wildcard Combinations

/authors/

Match the entry exactly.

/end-wild/*

/authors/*/

/middle/*/wildcard/

/authors/*/cookbooks/

Match an imbedded wildcard, but exact entry 
following the wildcard.

/*.extension

/*.gif/

Match any entry with the listed extension.

/entry.*

/index.*/

Match any entry with the listed filename and 
a wildcard extension.
