Class ServletDetectionFilter

java.lang.Object

com.netflix.zuul.ZuulFilter

org.springframework.cloud.netflix.zuul.filters.pre.ServletDetectionFilter

All Implemented Interfaces:

com.netflix.zuul.IZuulFilter, Comparable<com.netflix.zuul.ZuulFilter>

public class ServletDetectionFilter
extends com.netflix.zuul.ZuulFilter

Detects whether a request is ran through the DispatcherServlet or ZuulServlet. The purpose was to detect this up-front at the very beginning of Zuul filter processing and rely on this information in all filters. RequestContext is used such that the information is accessible to classes which do not have a request reference.
