well i managed to make it being cached using specific rule.
and your rule should do the trick
but look at the difference between our rules:
refresh_pattern -i ^http://www\.lsi\.com/.*AssetMgr\.aspx\?asset.* 4320
70% 10080
                                 leave the address ^^ alone
  refresh_pattern . 0 20% 4320 ignore-no-store ignore-no-cache
ignore-private ignore-auth override-expire reload-into-ims
                                 ^
your minimum time that you are using is 0 so you can try it for 2
minutes also in the case you are breaking the http protocols.

i must tell you that a proxy with this kind of settings on the "."
pattern can lead to a lot of troubles for the users.
so for for problematic sites that do not allow or want to be cached you
dont need to make your whole server a mess of wrong refresh patterns.

it's my line of thinking and it can also be a bug in the squid server
but i did mange to cache the file using the 3.2.0.5.
and i think that also the older versions will do the trick on this
specific case.

i have couple(more then you can think) of sites i made a specific
refresh patterns because they were worth it...
