You can use predicates in Spring Cloud Gateway to match an incoming request to a route configuration. For example, you can match based on the HTTP Method or URL path of the request.
The open-source Spring Cloud Gateway project includes a number of built-in predicates that can be used in Spring Cloud Gateway for VMware Tanzu.
For a complete list, see the Spring Cloud Gateway OSS documentation.
