Right, it wouldn't get expanded inside attributes.
I hadn't thought of that particular consequence of changing the URL
format; URL=view didn't used to create a new session.

So the trick is to find the current URL?  This is untested, but something
like this should work, I think:

MyComponent>>printHtmlTo: context
  session response
	headerAt: 'Location'
        put: 'view', context actionQuery;
        headerAt: 'Retry-After'
        put: '3'.

  super printHtmlTo: context.

Let me know how it goes.
