apachectl graceful in the crontab?

reverse-proxy to a DNS-name, and let DNS do the load balancing.

to have apache re-read the config, the other way is
/bin/kill -HUP `cat <path-to-pid-file>
and there's isn't a way for it to only reload the proxy changes or just
a part of the config and it is questionable why would apache have a way
to only reload a part of the config. No reason to support that.

Posted by Jignesh Badani <jb...@mmsa.com>.
Thanks Joost,
I am not so confident about "apachectl -k graceful". I was actually
referring to something within the Apache runtime. The parent process polls
the config files or a file with just proxy rules for changes and
communicates it to the child processes.
But since you have mentioned it, are you aware of any medium to big site
using "apachectl -k graceful " on a daily basis and during peak hours.
Also we are using a Netegrity Siteminder agent and they do not
recommend/support apache recycle using graceful.
About the DNS round-robin, well we could have used it if it was smart
enough to route a subsequent user request to the same backend server which
established the user session in the first place. I mean load-balancing and
routing request based on session information in the request header (or a
session cookie).
Thanks again.
