[undertow-dev] About response time in access log

Hi, everyone. Now Undertow AccessLogHandler is not supported Response time(%D/%T), right? I simply implemented it, but I'm not sure.. https://github.com/emag/undertow/commit/6401d61e3fcb5ce739ce4f30ae0d6fb3a... My code is 1) Add startTime:long field in HttpServerExchange 2) Initialize startTime and assign System.currentTimeMillis to it in HttpServerExchange#<init> 3) Create ResponseTimeAttribute and its readAttribute return (System.currentTimeMillis - exchage.getStartTime) Is it too simple? ----- I checked handler chain stack trace on WildFly Beta1. (default I/O-3) io.undertow.server.handlers.resource.ResourceHandler.handleRequest(ResourceHandler.java:76) (default I/O-3) io.undertow.server.handlers.PathHandler.handleRequest(PathHandler.java:90) (default I/O-3) io.undertow.server.handlers.accesslog.AccessLogHandler.handleRequest(AccessLogHandler.java:93) [...] <Some Handlers> -> AccessLogHandler -> PathHandler -> ResourceHandler If PathHandler and ResourceHandler(or another process) take a long time, my idea doesn't work.
