Summary

0001057: shutdown-wait-strategy

Description

<shutdown-wait-strategy>request</shutdown-wait-strategy>

  start rejecting all new conenctions with a 503, allow currently
  active connections to finish, for the maximum time specified with shutdown-wait-max.

<shutdown-wait-strategy>session</shutdown-wait-strategy>

  start rejecting all conenctions without a session with a 503, allow connections with a session,
  for the maximum time specified with shutdown-wait-max.

For the second case, mod_caucho and the LoadBalanceServlet would need a dead-time of 0 or the presence of a special signal from the backend indicating that the server is not dead for requests with a session.

Notes
(0001308) sam 06-26-06 13:48 edited on: 06-26-06 13:51	Since there is already startup-mode, and redeploy-mode, it should be named shutdown-mode: <shutdown-mode>session</shutdown-mode> <shutdown-mode>request</shutdown-mode> <shutdown-mode>immediate</shutdown-mode> New applications could automatically roll across the cluster with the addition of a shutdown-wait-start: (session-timeout * (cluster-index % 8))

(0001373) ferg 07-06-06 16:19	Add control item to LoadBalanceServlet to only let old sessions through. So add this logic to the front-end, not the backend.

(0001383) ferg 07-12-06 09:54	implemented by enableSessionOnly() on the load balancer.
