Doesn't the existing refresh_pattern overrides do the job as well? Or is
there any specific reason you need this on a per-request basis rather than
based on what is being requested?

To be safe this logics needs to be moved into the proxy rather than the
client (crawler in your case).

One way I see this done "proper" is similar to the redirector interface we
have today, but instead of rewriting the URL to be requested only the
cache key URL is rewritten.
