Note — To match the literal version of any of the special characters, the character must be
preceded by a backslash “\”. For example, to exactly match a period “.” the regular
expression must use “\.” as in “\.example\.com”. However, the appliance does not support
using a backward slash to escape a forward slash. If you need to use a forward slash in a
regular expression, type the forward slash without a backward slash.
( ) Group characters in a regular expression.
For example:
(abc)* matches abc or abcabcabc
“...” Literally interprets any characters enclosed within the quotation marks.
\ Escape character.
