+This function implements the read through cache behavior. On failure of retrieval this callback will be called. 
+You are responsible for populating the result object provided. This result object will then be stored in the server and
+returned to the calling process. You must clone the memcached_st in order to
+make use of it. The value will be stored only if you return
+MEMCACHED_SUCCESS or MEMCACHED_BUFFERED. Returning MEMCACHED_BUFFERED will
+cause the object to be buffered and not sent immediatly (if this is the default behavior based on your connection setup this will happen automatically).
