No. What probably will be supported in a later Squid version is relaxed refreshes where Squid will give a slightly old object to some clients while refreshing cached objects. This will however only make a difference on frequently accessed object where there is more than one concurrent request for the same URL as there still will be the requirement that there is a active client for each refresh (only the second client while the object is refreshed can be optimized by this approach). The problem with proactive refreshes is bandwidth management. All implementations in other cache servers known to the Squid developers tends to end up wasting very large amounts of bandwidth on objects which in the end is never accessed again by the clients, and until a reasonable approach to avoid this is found the Squid developers does not find any reason why to implement proactive refreshes in Squid.
