opening frames in new window

I have a frame page containing a left frame, a right frame and a 2 frames in the middle named mid_head and mid_body.

Is there a way I could open a new window containing only mid_head and mid_body without going back go the server first? (mid_head and mid_body is filled from a database, i'd like a user to be able to open a new window with these two frames without going back to the server again...)

perhaps this is a javascript stuff?

I hope i'm clear enough...

I don't think you can do that. You can certainly open them in a new window, but it requires the round trip back to the server. I don't think that the browser provides a way to reference a cached page. Besides, the user could have caching disabled (of course, that would be stupid, but you could do it).
