-        In load balancing, how can I separate reads from writes? Is a
-        backend-server a remote MySQL machine ? You would think so, but
-        from another post in this forum, it looks like the separation of
-        reads from writes has not been implemented yet, so I am not
-        clear as to the distinction between backend-servers and
-        read-only servers.

-        In version 0.6.0 there is no separation between read and writes
-        and it is up the user to make sure that only reads are sent to
-        the proxy. In the next releases we will add connection pooling
-        and read/write splitting to make this more useful. See also
