Regular Expressions
Some Configuring Class Maps and Configuring Inspect Maps can specify regular expressions to match
text inside a packet. Be sure to create the regular expressions before you configure the class map or
inspect map, either singly or grouped together in a regular expression class map.
A regular expression matches text strings either literally as an exact string, or by using metacharacters
so you can match multiple variants of a text string. You can use a regular expression to match the content
of certain application traffic; for example, you can match body text inside an HTTP packet.
