I think squid will send an IMS when it thinks object is stale.
I, for one, force squid to always do IMS instead of full query
on potentially large files (part of squid.conf):

refresh_pattern -i [.]mpeg$ 2880 50% 2880000 override-lastmod reload-into-ims
                                                              ^^^^^^^^^^^^^^^
BTW. reload-into-ims is cool, ignore-reload makes squid even more speedy for
users but have much worse "worst case" scenario: object won't be updated,
even by reload, until it's stale.

It will be extremely clever to return object and do IMS in parallel,
so that user gets (potentially stale) object only once, while squid is
verifying "in background" that there isn't a newer one.
But there is no such option now. Henrik must be swamped by
silly feature requests like this ;)
