Sorry, Amos. This was sarcasm. May be, not too relevant.

Maybe. However, this greatly increases the content duplication. Аgree?

:) Really sorry.

Sometimes our experiments scratching the hell out of the display content
in browsers. That's what I called "break the Internet". :) But
seriously, we're trying to find a compromise between a high cache and
the desire to satisfy customers. It seems to me, mutually exclusive things.

Meanwhile, Amos, I still believe that the team should now, in 2016, to
seriously reconsider attitude to compress the content and possibly
revise Vary processing algorithms in favor of more vysokgo cache hit
ratio. Under the conditions of high-speed Internet only a high hit ratio
justifies the use of caching proxy.
