Why not adjusting cache_remove_url accordingly? It does nearly the
same and
has the same prototype.
Nearly the same, but not enough. cache_remove_url() only takes effect
if a previous cached entry was found, while cache_invalidate() is
unconditional.
As it turns out, invalidating the entry unconditionally is wrong, as
we need to do the invalidation only on 2xx. This means this code needs
to be changed, waiting for Roy to confirm the exact behaviour before
changing it.
