Hi Chhaya,

I see why. Looking at the code, you need to pass in the original
projection parameters. Otherwise, the MapRequestHandler doesn't know
where to pan *from*. It doesn't keep track of state between requests.
  If you don't pass in the projection parameters, it will pan from the
original projection parameters it was initially configured with in the
properties.

Same thing with the RECENTER command.
