It was too delayed reply from my side.. but yes, I found something to cheer for after this solution.
Thanks Sasi !! This might help someone.
What I exactly looking for was, my client has two separate servers for Production & UAT. (Normal Case)
Both the servers has qlikview server installed on it. Its a constant support environment where we do development as per user requirement & send them UAT Server URL for data validation. & once UAT is done we update (upload) the application on Production server.
we gave users the direct accesspoint URL of application.
