For more information, see <a href="https://docs.aws.amazon.com/waf/latest/developerguide/classic-waf-chapter.html">AWS WAF Classic</a> in the developer guide.</p> <p> <b>For the latest version of AWS WAF</b>, use the AWS WAFV2 API and see the <a href="https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html">AWS WAF Developer Guide</a>. With the latest version, AWS WAF has a single set of endpoints for regional and global use. </p> </note> <p>Creates a <code>Rule</code>, which contains the <code>IPSet</code> objects, <code>ByteMatchSet</code> objects, and other predicates that identify the requests that you want to block. If you add more than one predicate to a <code>Rule</code>, a request must match all of the specifications to be allowed or blocked. For example, suppose that you add the following to a <code>Rule</code>:</p> <ul> <li> <p>An <code>IPSet</code> that matches the IP address <code>192.0.2.44/32</code> </p> </li> <li> <p>A <code>ByteMatchSet</code> that matches <code>BadBot</code> in the <code>User-Agent</code> header</p> </li> </ul> <p>You then add the <code>Rule</code> to a <code>WebACL</code> and specify that you want to blocks requests that satisfy the <code>Rule</code>. For a request to be blocked, it must come from the IP address 192.0.2.44 <i>and</i> the <code>User-Agent</code> header in the request must contain the value <code>BadBot</code>.</p> <p>To create and configure a <code>Rule</code>, perform the following steps:</p> <ol> <li> <p>Create and update the predicates that you want to include in the <code>Rule</code>. For more information, see <a>CreateByteMatchSet</a>, <a>CreateIPSet</a>, and <a>CreateSqlInjectionMatchSet</a>.</p> </li> <li> <p>Use <a>GetChangeToken</a> to get the change token that you provide in the <code>ChangeToken</code> parameter of a <code>CreateRule</code> request.</p> </li> <li> <p>Submit a <code>CreateRule</code> request.</p> </li> <li> <p>Use <code>GetChangeToken</code> to get the change token that you provide in the <code>ChangeToken</code> parameter of an <a>UpdateRule</a> request.</p> </li> <li> <p>Submit an <code>UpdateRule</code> request to specify the predicates that you want to include in the <code>Rule</code>.</p> </li> <li> <p>Create and update a <code>WebACL</code> that contains the <code>Rule</code>. For more information, see <a>CreateWebACL</a>.</p> </li> </ol> <p>For more information about how to use the AWS WAF API to allow or block HTTP requests, see the <a href="https://docs.aws.amazon.com/waf/latest/developerguide/">AWS WAF Developer Guide</a>.</p>

    Args:
        name: <p>A friendly name or description of the <a>Rule</a>. You can't change the name of a <code>Rule</code> after you create it.</p>
        metric_name: <p>A friendly name or description for the metrics for this <code>Rule</code>. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change the name of the metric after you create the <code>Rule</code>.</p>
