活着的Dropwizard

Question

I understand Jetty can be configured via the config file within Dropwizard, however I cannot find a way to enable Keep-Alive, any suggestions on how to implement this rather than a custom filter?

server:
  type: simple
  applicationContextPath: /
  adminContextPath: /admin
  connector:
    type: http
    port: 8080
  gzip:
    bufferSize: 8KiB

Answer 1

HTTP keep-alive support is available by default in Jetty when using HTTP/1.0

The use of HTTP/1.0 keep-alive is dependent on the HTTP Client (its chosen HTTP version support level, and the headers it sends).

Note that keep-alive is an invalid term/concept/setting/header when using HTTP/1.1 (it has no meaning on HTTP/1.1).

HTTP/1.1 is connection persistent by default, and you would need to pass a Connection: close header to request that the connection is closed after the current HTTP exchange.
