Appendix A CSG2 Command Reference
match method
• By default, the method match patterns are case-sensitive. For example, if you define the following
method match pattern:
match method get
but the actual method keyword is GET, then the match fails and the CSG2 does not accept or process
the flow.
If you do not want the method match patterns to be case-sensitive, configure the no ip csg
case-sensitive command.
You can specify up to 8192 match patterns.
The following table shows and describes the special characters that you can use in the method-name
argument in method match patterns.
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.
