Logical rule statements
Use logical rules statements to combine other statements or negate their results. Every logical rule statement takes at least one nested statement.
To logically combine or negate rule statement results, you nest the statements under logical rule statements.
Logical rules statements are nestable. You can nest them inside other logical rule statements and use them in scope-down statements. For information about scope-down statements, see Scope-down statements.
Note
The visual editor on the console supports one level of rule statement nesting, which works for many needs. To nest more levels, edit the JSON representation of the rule on the console or use the APIs.
This table describes the logical rule statements and provides guidelines for calculating web ACL capacity units (WCU) usage for each. For information about WCUs, see Amazon WAF web ACL capacity units (WCUs).
