Hi, We have a tomcat on an amazon service with for now a ELB L4 (tcp loadbalancer, with ssl offloading) before it
That works for the most part just fine, except we don't know that we are in ssl mode or not Our application have support for that to look at the x-forwarded-proto header (and some other fallbacks) to see what is really the scheme the end users uses So we switch to a ELB L7 load balancer which is the http load balancer that will add those x-forwarded-proto for us. And yes i checked they are on all the reques tthen. This seems to work for all kind of connections to servlets/files/filters and so on except websockets.... Suddenly if we switch that on then all the websocket connections are returning 404 (i see that in the browser and in the tomcat access log) Can't find any other thing in the log files that would give me a clue what is happening Does anybody has an idea why suddenly the http upgrade stuff to websockets (wss protocol) are suddenly seen as 404/NOT_FOUND ? -- Johan Compagner Servoy
