I started a thread back in the 2.x days about your point #1: https://www.varnish-cache.org/lists/pipermail/varnish-misc/2011-May/020507.html The naive purge I came up with may not be optimal for 3.x (and may not have been best for 2.x!) As you'll see through that thread, the opinion of the list seemed to be that just writing VCL to do it wasn't the way forward. I'm not *convinced* this is the case however. > 2.
