PHP.INI & session.save_path & ElastiCache

Question

Below is from http://php.net/manual/en/memcache.ini.php#ini.memcache.hash-strategy

session.save_path string Defines a comma separated of server urls to use for session storage, for example "tcp://host1:11211, tcp://host2:11211".

Question: AWS ElastiCache gives you node endpoints and a configuration endpoint (which I believe is a DNS CNAME to the ElastiCache Cluster).

If I put the configuration endpoint value into session.save_path will this mean Sessions use the Cluster rather then a specific node and therefore always use an active node?

I understand if a node is rebooted/removed the data held will be lost and therefore sessions on that node will be lost.

thank you!

No, it does not work that way. You need to use the Amazon memcached client that has support for Auto Discovery.
