About Operators
There are a number of arithmetic and string operators. The Not check box is an inversion operator that results
in a match for any value except the configured condition.
These operators can be used in conjunction with Anti-Evasive Measures. For example, you might use the
Equals String operator with Convert to Lowercase or Normalize URI Path in Anti-Evasive Measures.
Ta b l e 3 5 describes the available operators for use with rules.
Response Header

current request.
To match against some aspect of the entire list of response header names,
leave the selection field empty.
To match against a particular header name, specify the name of the
header in the selection field to the right of the colon.
Response Content
Length
No Refers to the size of the response payload.
Response Payload No Refers to the Web page content that is displayed to the user.
Portal Hostname No Refers to the virtual host name of the Secure Mobile Access portal which
accepts the request from the client.
To create a rule chain that applies to a particular virtual host, one rule
would match the host and another would specify other criteria for the
match.

portal which accepts the request from the client.
