Sorry Mark for late reply..

You are right this is like a normal link, and yes that is _exactly_ we need,
but we also need parameters to be specified for this as this is hostless.

The moment I add 'params" core will do different connections which do not
work for us.

I am okay if you have something else in mind which solves our problem :)
