Is there any option to ignore the cache-control header "only-if-cached" when sent by a client? Requests with the above gets a 504 Gateway time-out and X-Squid-Error: ERR_ONLY_IF_CACHED_MISS 0. "You have issued a request with a "only-if-cached" cache control directive. The document was not found in the cache, or it required revalidation prohibited by the only-if-cached directive." I know cache-peer directive can take the option "allow-miss" but this setup has two-way peering and worried about forward loops. Appreciate any help. Thanks.
