Hi Everyone,
I know you can use acl's to take a request for a file and send it to a
different backend than the normal requests go to, but I was wondering
can an acl be setup so that when a request for a file, say update.php,
is called via the external url, for example:
http://www.example.com/update.php
Instead of sending it to a single server can you send it to all of the
backend servers at the same time?
For example, if you have a cache on each backend that needs to be
updated all at the same time when a post is made from a visitor? So
lets say my visitor hits backend http://b1.example.com/my/own/blog where
they post a comment and I have a script setup so that when the post
request is made it calls http://www.example.com/update.php to update the
cache directory with the new content. With a single cache server this
normally wouldn't be a question, but having the cache on each backend
makes it more difficult and I am curious if I can have the call for
update.php sent to all the backends instead of my having to run a cron
job on each system to make the call every minute or so.
Thanks everyone
Joe
