-available.

 Makes the default hashing algorithm for keys use MD5. The value can be set to either MEMCACHED_HASH_DEFAULT, MEMCACHED_HASH_MD5, MEMCACHED_HASH_CRC, MEMCACHED_HASH_FNV1_64, MEMCACHED_HASH_FNV1A_64, MEMCACHED_HASH_FNV1_32, MEMCACHED_HASH_FNV1A_32, MEMCACHED_HASH_KETAMA. The behavior for all hashes but MEMCACHED_HASH_DEFAULT is identitical to the Java driver written by Dustin Sallings.
 
+=item MEMCACHED_BEHAVIOR_DISTRIBUTION
+
+Using this you can enable different means of distributing values to servers.
+The default method is MEMCACHED_DISTRIBUTION_MODULA. You can enable
+consistent hashing by setting MEMCACHED_DISTRIBUTION_CONSISTENT. 
+Consistent hashing delivers better distribution and allows servers to be 
+added to the cluster with minimal cache losses. 
+
+=item MEMCACHED_BEHAVIOR_CACHE_LOOKUPS
+
+Memcached can cache named lookups so that DNS lookups are made only once.
+
+=item MEMCACHED_BEHAVIOR_SUPPORT_CAS
+
+Support CAS operations (this is not enabled by default at this point in the server since it imposes a slight performance penalty).
+
+=item MEMCACHED_BEHAVIOR_POLL_TIMEOUT
+
+Modify the timeout value that is used by poll(). The default value is -1. An signed int pointer must be passed to memcached_behavior_set() to change this value. For memcached_behavior_get() a signed int value will be cast and returned as the unsigned long long.
+
+=item MEMCACHED_BEHAVIOR_USER_DATA
+
+This allows you to store a pointer to a specifc piece of data. This can be
+retrieved from inside of memcached_fetch_exectue(). Cloning a memcached_st
+will copy the pointer to the clone.
+
+=item MEMCACHED_BEHAVIOR_BUFFER_REQUESTS
+
+Enabling buffered IO causes commands to "buffer" instead of being sent. Any
+action that gets data causes this buffer to be be sent to the remote
+connection. Quiting the connection or closing down the connection will also
+cause the buffered data to be pushed to the remote connection.
