The value must be unique for forwarding policies of the same listener. This parameter will take effect only when <strong>enhance_l7policy_enable</strong> is set to <strong>true</strong>.

</li><li><p>If <strong>enhance_l7policy_enable</strong> is not enabled, forwarding policies are automatically prioritized based on the original policy sorting logic. The priorities of domain names are independent from each other. For the same domain name, the priorities are sorted in the order of exact match (<strong>EQUAL_TO</strong>), prefix match (<strong>STARTS_WITH</strong>), and regular expression match (<strong>REGEX</strong>). If the matching types are the same, the longer the URL is, the higher the priority is. If a forwarding policy contains only a domain name without a path specified, the path is <strong>/</strong>, and prefix match is used by default.</p>
</li><li><p>If <strong>enhance_l7policy_enable</strong> is set to <strong>true</strong> and this parameter is not passed, the priority will be a sum of 1 and the highest priority of existing forwarding policy in the same listener by default. If the highest priority of existing forwarding policies is the maximum (10,000), the forwarding policy will fail to be created because the final priority for creating the forwarding policy is the sum of 1 and 10,000, which exceeds the maximum. In this case, specify a value or adjust the priorities of existing forwarding policies. If no forwarding policies exist, the highest priority of existing forwarding policies will be set to 1 by default.</p>
