You can specify up to 8192 match patterns.

The following table shows and describes the special characters that you can use in the method-nameargument in method match patterns.

Convention	Description
*	Zero or more characters.
+	Zero or more repeated instances of the token preceding the +.
?	Zero or one character.
\character	Escaped character.
	Examples:
	\?	Match on a question mark (\<ctrl-v>?)
	\+	Match on a plus sign
	\*	Match on an asterisk
	\a	Alert (ASCII 7)
	\b	Backspace (ASCII 8)

	\n	New line (ASCII 10)
	\r	Carriage return (ASCII 13)
	\t	Tab (ASCII 9)
	\v	Vertical tab (ASCC 11)
	\0	Null (ASCII 0)
	\\	Back slash
Bracketed range [0-9]	Matching any single character from the range.
A leading ^ in a range	Do not match any in the range. All other characters represent themselves.
.\x##	Any ASCII character as specified in two-digit hex notation.
	For example, \x3f yields a ? for a one-character wild card match.

When configuring a map, keep the following considerations in mind:

•You cannot specify different types of match patterns in a given map. For example, a map can include one or more match header statements, but it cannot include both match header statements and match url statements.

•You can specify up to three maps in a given policy: one for header matching, one for method matching, and one for URL matching. For example, the following is a valid configuration:

ip csg map HOSTMAP

match header host1 value *.2.*.44

!

ip csg map URLMAP

match url */mobile/index.wml

!

ip csg policy MAP-POLICY map HOSTMAP

map URLMAP
