Hello,
I've been making great progress with CometProcessor on Tomcat 6.0.29.
I have a question about handling timeouts (and I did review this
thread: http://www.mail-archive.com/users@tomcat.apache.org/msg55616.html).
I want my clients to connect and stay connected for a very long time,
but I do need to have my server time the connections out periodically.
When I request.setAttribute("org.apache.tomcat.comet.timeout",
timeout), I do indeed receive a CometEvent.EventType.ERROR, but I can
find no way to gracefully tell the client that everything is OK and I
just want them to back off for a while then reconnect.
When I do this:
...
response.sendError(HttpServletResponse.SC_REQUEST_TIMEOUT, "Timed out.
Please reconnect");
response.flushBuffer();
event.close();
...
the client does not receive the response. They only sense an
unceremonious connection close - which, if through routers, may take
quite some time to be detected.
How can I hook into the timeout to send the client a short response
before connection close?
Is there a better way to do this? Should my application handle these
timeouts, and use the comet.timeout as a longer safety net?
Much appreciated.
