[sr-dev] DB API and connection keepalive

Hi *, What would be the suggestions regarding having a process / thread that can be used to ping (keepalive) a connection to a particular db backend. I am specifically looking at coding something for mysql (our firewall is closing connections to mysql if they are idle for longer than 30mins). I would like to have a process that would go through all connections and "ping" them every so often. I would imagine each DB impl can either ignore the ping function or actually do something with it. I would imagine this will be useful for a few backend db implementations. Any input before I go ahead? Cheers Jason
