Thanx Nik,
You're right, to make a connection pool will need a C code source.

I found some links on the net with different packages to do that, 
like "sql relay" who offer a package "sqlrelay-0.32" which have different 
type of server connections including a server connection pool.

But i don't know its limitations at the moment. 
I'm trying to implement it, but still stuck with it.
Hope it works.

Fat.
