Anders, Thanks for the link. This helps.
I'm going to put my vote in for this to be at least discussed at next months User Group meeting. I just took a look through the list archives, and it seems like I'm not the only one looking for this functionality :)

If the origin returns a 304 Not-Modified Varnish will serve the object from cache and reset the TTL counter? Possible, well, sort of. Some work has been made on this, but it hasn't been merged into mainline, let alone released. See https://www.varnish-cache.org/trac/wiki/BackendConditionalRequests for more information. The Varnish devs may have more information, but I don't think we can expect a timeline commitment yet.
