All Implemented Interfaces:

public class HystrixRequestLogViaResponseHeaderServletFilter
extends java.lang.Object
implements javax.servlet.Filter

Add HystrixRequestLog.getCurrentRequest().getExecutedCommandsAsString() to response as header "X-HystrixLog".

This will not work if the response has been flushed already.

Install by adding the following lines to your project web.xml:

 <filter>
     <display-name>HystrixRequestLogViaResponseHeaderServletFilter</display-name>
     <filter-name>HystrixRequestLogViaResponseHeaderServletFilter</filter-name>
     <filter-class>com.netflix.hystrix.contrib.requestservlet.HystrixRequestLogViaResponseHeaderServletFilter</filter-class>
   </filter>
