All the custom filters that can be pure 'before' filters are implemented in https://github.com/spring-cloud/spring-cloud-gateway/blob/main/spring-cloud-gateway-server-mvc/src/main/java/org/springframework/cloud/gateway/server/mvc/filter/BeforeFilterFunctions.java[org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions] and adapted in `FilterFunctions` as request processors.

 There are additional `*FilterFunctions` classes for optional filters that are documented along with each filter.
