.\x##

Any ASCII character as specified in two-digit hex notation.

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

 

 

In this example, a flow must match both HOSTMAP and URLMAP in order to match policy

 

 

MAP-POLICY.

 

 

Examples

The following example shows how to specify HTTP header match patterns for map HDR1. In this

 

 

example, the header match is TRUE only for host www.cisco.com and user agent myagent. Any other

 

 

combination of host and IP address matches FALSE:

 

 

ip csg map HDR1

 

 

match header Host www.cisco.com
