cache parms

Is anyone aware of *specific* cache sites which forcefully ignore page
expiration in a way which would throw off content providers' hit counting?
If so, I would like to talk with the cache admin to understand a few things.

i have a modified squid that *specifically* strips out expire pragmas and
continue serving pages that are cached but used to be marked with an
expire.

you can also apply the same rules with dynamic content (eg .asp documents)
by stripping the "header" and/or "footer" that is customized and just
feeding the cached "body" with a newly formed "header"/"footer".

I am not asking if it can be done. I am asking for specific cases where it
is current practice. I.e.

  "Yes, all of Texas gets its connectivity via a OC12 from Botswana, and
  runs an expire-proof Squid at the border."

to use the quoting style of randy,

Yes, all of ogn.net (and it's downstreams) gets its connectivity via
various transit providers and peers, and runs an expire-proof squid at
it's US and Australian border, with seven other "sub-caches" feeding
from the mother squids.
