how to control the destination of a new page?

[hnalbert]

In general, we submit a form to asp, asp generate a new form showing in the same brower window and overcasting the previous one. But how to let the new page show in a new window so we can see the previous one? what's the basic rule to direct the destination showing window of a new page?
