If you are OK with hard-coded usage time slots for each peer, then I would use two[1] "time" ACLs and cache_peer_access rules. Look for "aclname time" in squid.conf.documented. You will have to generate a list of (24*2/3=16) staggered time slots for each of the two ACLs, but it should work. This may be the simplest solution. [1] You need two ACLs for three peers because the third peer should get the requests that the first two peers were not allowed to get. ---- With a modern Squid, you could also implement this using a more flexible (and more expensive, on several layers!) architecture with two ACLs: 1. An external ACL that returns the right cache peer name to use via a keyword=value annotation API. This always-matching ACL should be attached to http_access or a similar directive that supports slow ACLs. Its goal is to annotate the request. You will need to write a script/program that will compute the right annotations based on time or some other factors. This is where the flexibility of this solution is coming from. 2. A "note" ACL attached to cache_peer_access directives, allowing access to peer X if the external ACL in item 1 returned use_cache_peer_=X. The "note" ACL is a fast ACL and, hence, can be reliably used with cache_peer_access. If you already have another external ACL, you may be able to piggyback annotations in item 1 to whatever that ACL is already doing. For more information, search for "keyword=value" and "acl aclname note" in your squid.conf.documented and see https://wiki.squid-cache.org/Features/AddonHelpers#Access_Control_.28ACL.29 HTH, Alex. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
