Than you can perform caching of sql queries?

We need a tool which could proxy sql requests from the clients to the mysql server and if the server came up with the error I sent this same query on another sql server.

Also interesting, but not a critical issue ssl encrypted connections to these proxies.

Now I'm using in a similar role haproxy it has a mechanism which polls the server excludes from the list those who did not answer correctly. But I want instead of every second check the health of servers just to handle the error code and if it appeared not to refuse a client and just try to run the same query on another server.
