No, it is not expected. Consider filing a bug report with Squid bugzilla and, if possible, attach an ALL,9 cache.log while reproducing the problem with a single wget or curl transaction. Please do not forget to specify your Squid version. If you can reproduce the problem with Squid v4 or v5, please mention that as well. > Wouldn't request header be available before > sending a query to store-id helper?

That plan would not work because the Store ID helper is consulted after the URL rewriter: https://wiki.squid-cache.org/SquidFaq/OrderIsImportant#Callout_Sequence Using custom headers is a much simpler/cleaner solution IMO.
