Appendix A CSG2 Command Reference
match url
– Do not forget that the entire pattern, including wildcards and UNIX string-matching special
characters, cannot exceed 128 characters.
You can specify up to 8192 match patterns.
The following table shows and describes the special characters that you can use in the pattern argument
in URL match patterns.
For WAP, the CSG2 supports only URL maps. Header maps and method maps are not supported.
When configuring a map, keep the following considerations in mind:
• We recommend that you configure the URL match pattern during your maintenance window, or
during off-peak hours.
• 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
