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.

Table 7-1:Wildcard Combinations

Wildcard	Example	Definition

/exact-match/	/authors/	Match the entry exactly.
/end-wild/*	/authors/*/	Match any ending wildcard.
/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.

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
