Alex, first of all, thank you for your clarification. > Squid does not know that the response headers and body have not changed. > Squid could, in theory, trust the URL+Vary+ETag+etc. combination as a > precise response identity, but it is a bit risky to do that by default > because ETags/etc. might lie.

Ok, now I know that only URL/Vary are taken into account when storing an object. > To be more accurate, Squid does not store multiple copies of (what Squid > considers to be) the same response -- only one object can be indexed per > URL/Vary.

Since in my case there's no Vary header and the object Full URL never changes, I',m starting to think about a bug (?!). > I do not know much about aufs -- that code has been neglected for a > while -- but perhaps aufs simply does not have enough time to delete its > old/unused files?

Uhm, are you saying that the the process of an object replacement on disk is not atomic? I mean: squid would store a new copy of the object while leaving the old copy deletion to cleanup task? If it's not, I still suspect a bug. I'm hesitant to to turn the store_log on, 'cause the performance impact. Btw, is there a specific debug_option? Thanks a lot.
