sessions in memcache with redundant server

Hi all, we are using memcache within php to store session but are worried if one of the memcache servers would fail that we would loose half of our session. While diggin the net I stumbled upon this bug report from late 2007 http://pecl.php.net/bugs/bug.php?id=11637. Inside the bug report there is a proposal for configuration options for using redudant memcache to store the sessions. Also the configuration options mentioned inside the thread seems to work (at least the + when configuring session.save_path inside php.ini, the mentioned & does not) but the sessions are not stored inside both memcache servers. I checked the content of the memcache servers with the script from here http://livebookmark.net/memcachephp/memcachephp.zip My questions now is if this feature ever got implemented and if where can I find some documentation? As I only configured php sessions handling with the infos I got from the bug report maybe I just did not do it right. For completness here are the relevent parts of the php.ini file and the conf.d/memcache.ini file memcache.ini extension=memcache.so [memcache] memcache.dbpath="/var/lib/memcache" memcache.maxreclevel=0 memcache.maxfiles=0 memcache.archivememlim=0 memcache.maxfilesize=0 memcache.maxratio=0 memcache.allow_failover = 1 memcache.session_redundancy = 2 php.ini extract session.save_handler = memcache session.save_path = "tcp://127.0.0.1:11211+tcp://127.0.0.1:11212" The + at least does not give me an error when I do a session_start(). Thanks in advance and Best Regards Sascha Müller
