Actionscript localconnection to database; using localhost

Hello,

I have been left with a flex product for a cd rom the wole thing will be published using zinc bu i need to get the debugging environment set up.

The previous developmer (who i cannot get hold of) used flashes localconnection object to access a sql server database. I know this somehow uses localhost but i am lost to how the two instances (dbin, dbout) were set up.



all i need is a good url clue on how to set up "dbin" and "dbout"
as for debugging the localconnection is susccessful because localhost is enabled

The access code goes something like.
