different target frames based on mode

[John Carlson]

Would something like the following be possible with mapserv?

I would like to have a different html frame target based on the
mapserv mode.  One target, called "main" will be used for
results of a query mode, and another target, called "right"
will be used for browse mode.

Is the target determined in the client/browser before mapserv runs?

Thanks,

John
