Rule
, which contains the IPSet
objects, ByteMatchSet
objects, and other predicates that identify the requests that you want to block. If you add more than one predicate to a Rule
, a request must match all of the specifications to be allowed or blocked. For example, suppose you add the following to a Rule
: An IPSet
that matches the IP address 192.0.2.44/32
A ByteMatchSet
that matches BadBot
in the User-Agent
header
You then add the Rule
to a WebACL
and specify that you want to blocks requests that satisfy the Rule
. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent
header in the request must contain the value BadBot
.
To create and configure a Rule
, perform the following steps:
Create and update the predicates that you want to include in the Rule
. For more information, see CreateByteMatchSet, CreateIPSet, and CreateSqlInjectionMatchSet.
Use GetChangeToken to get the change token that you provide in the ChangeToken
parameter of a CreateRule
request.
Submit a CreateRule
request.
Use GetChangeToken
to get the change token that you provide in the ChangeToken
parameter of an UpdateRule request.
Submit an UpdateRule
request to specify the predicates that you want to include in the Rule
.
Create and update a WebACL
that contains the Rule
. For more information, see CreateWebACL.
