It is there (storeMaintainSwapSpace.). The expire date is calculated
both as object life time and last reference. See storeCheckExpired.

In storeMaintainSwapSpace a object is regarded as expired if:
1. The object lifetime has expired
2. The object has not been accessed within the LRU max age. LRU max age
is based on reference_age in squid.conf, and how close to cache_swap_max
your cache is.
