Some operations are applied to all objects, some are applied to only
cached HIT objects when served.

The refersh_pattern regex is applied on the cache storage key. That used
to be only URL, but in Squid-3.4 and later with store-ID helper you can
adjust the key.

If you are able to determine in the store_id_program helper which
objects meet your criteria you can set the store ID to a have a tag
prefix on the URL (eg BIG_http://example.com/movies.mp4 or
SMALL_http://example.com/index.html) and have your refresh_pattern regex
check for it (refresh_pattern ^BIG_ , refresh_pattern ^SMALL_ ).
