I am new to Varnish so so the question might me a bit poorly stated. I am
trying to configure Varnish so that serving an URL from cache depends on
the freshness of another URL given as argument to the original URL.

For example, the original URL might look like:

If I have seen this URL before and cached its result, I would like
Varnish to use the cached data only if: 

has not changed since the result was cached.

Any pointers would be greatly appreciated.
