Well, I think I may have come up with a solution.  Here it is, both in
the hope that it might be useful and in case I've missed something subtle.

I responded with a WAGenericResponse that contained my frameset
HTML, including URLs to the image and to the next page of my
application.  The part that I was struggling with was what URL to
use for the next page.

It ends up that I could use WAHtmlRenderer>>#urlForAction: to do what
I needed (which makes sense now that I know).

Here's something like my code for creating the response.

	| response |
	response _ WAGenericResponse new
		nextPutAll: '<html><frameset rows="10%, 90%">';
		nextPutAll: '<frame src="';
		nextPutAll: (html urlForAction: [self call: PrintOrFax new]);
		nextPutAll: '" />';
		nextPutAll: '<frame src="';
		nextPutAll: self imageUrl;
		nextPutAll: '"/>';
		nextPutAll: '</frameset></html>'.

	self session returnResponse: response.
