About Operators

There are a number of arithmetic and string operators. The Not check box is an inversion
operator, which results in a match for any value except the configured condition.
These operators can be used in conjunction with Advanced Operations. For example, you
might use the Equals String operator with Convert to Lowercase or Normalize URI Path in
Advanced Operations.
