I am having a problem with Varnish 3.x probe page from a SpringBoot application (1.4). Varnish is failing to detect the probe page (returns 503 SERVICE NOT AVAILABLE) and consequently fails to route. When I manually ping the probe URL, it works fine, but Varnish is flagging the probe page as being down. Removing the probe page, everything works fine. Pointing to a static probe page (my.css) or any other static or dynamic URL fails. Looking at the logs, the response header looks like this: HTTP/1.1 200 Content-Type: text/plain;charset=utf-8 Content-Length: 72 Date: Wed, 01 Feb 2017 15:20:48 GMT Proxy-Connection: Keep-Alive Connection: Keep-Alive
Comparing this to other working (non Spring Boot) applications, the only difference is that the working applications have an OK after the response, and the bad ones don't: HTTP/1.1 200 OK Does that mean anything? For example, here is a good one: HTTP/1.1 200 OK Date: Wed, 01 Feb 2017 14:04:18 GMT Last-Modified: Fri, 11 Nov 2016 22:00:02 GMT Content-Type: text/css Content-Length: 129 Server: Jetty(9.3.z-SNAPSHOT) Proxy-Connection: Keep-Alive Connection: Keep-Alive Not sure where else to look! Any clues?
