Use pattern sets and data sets

Advanced policy expressions that take pattern sets or data sets as an argument can be used to perform string matching operations.

The usage is as follows:



  • <text> is the expression that identifies a string in a packet. Example: HTTP.REQ.HEADER(“Host”).
  • <operator> is one of the operators described in the Pattern Set Types table pdf.

For sample usage, see Sample Usage.
