What is Per-URI policy in Application Gateway Web Application Firewall (WAF)?

For even more customization down to the URI level, you can associate a WAF policy with a path-based rule. If there are certain pages within a single site that require different policies, you can make changes to the WAF policy that only affect a given URI. This might apply to a payment or sign-in page, or any other URIs that need an even more specific WAF policy than the other sites behind your WAF.

As with per-site WAF policies, more specific policies override less specific ones. This means a per-URI policy on a URL path map overrides any per-site or global WAF policy above it.
