Responses denied by this directive will not be served from the cache
(but may still be cached, see store_miss). This directive has no
effect on the responses it allows and on the cached objects. This
directive is applied to both regular from-cache responses and responses
reused by collapsed requests (see collapsed_forwarding).
Please see the "cache" directive for a summary of differences among
store_miss, send_hit, and cache directives.
Unlike the "cache" directive, send_hit only supports fast acl
types. See https://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
For example:
# apply custom Store ID mapping to some URLs
acl MapMe dstdomain .c.example.com
store_id_program ...
store_id_access allow MapMe
# but prevent caching of special responses
# such as 302 redirects that cause StoreID loops
acl Ordinary http_status 200-299
store_miss deny MapMe !Ordinary
# and do not serve any previously stored special responses
# from the cache (in case they were already cached before
# the above store_miss rule was in effect).
send_hit deny MapMe !Ordinary
