win.addServerFrame()

    s = w.addServerFrame(num)

Creates a new serverFrame, adds it to the window, and returns a pointer to it. Optionally, the num parameter will create as many serverFrames as desired, add them to the window, and returns the address of the first one. All serverFrames of a window are referenced in the "serverFrames[]" array, an internal variable of each window. Don't use "serverFrames[0]"; it is used by the default window functions and targets its WebServer requests to the window's displayFrame.
ServerFrames added by "addServerFrame()" behave just like serverFrames created with "new". They are treated as a group when the win method "submit()" is called, and the leftmost button on the window turns red until all submitted serverFrames of that window have returned.
