This is from include/tbl/http_headers.h in the Varnish code base.

I'm not going to break it down in details, but that's basically where
we declare well-known headers and when to strip them when we perform a
req->bereq or beresp->resp transition.

In this case, we strip the cache-control header from the initial
beresp when it is a cache miss.
