I am aware that all proxies can use a single memcache server. If I choose to install memcache on every proxy server, which memcache instance does the proxy host consult for route information? The one that is running locally or all memcache servers in the installation?
I am trying to determine how many proxy servers should have memcache installed. Would obviously like to have more than one memcache server for continuance reasons and am wondering what issues might arise if there is memcache running on each proxy.
