Hi, Does squid support proactive refresment? When there is a request and the object is stale, the cache will fetch the object from the server. However, the response time experienced by user will be slower. In Proactive refreshment, the cache will update the stale objects without being triggered by user requests. So, when later there is a request from the user, the proxy server can return the requested object directly. In the paper "refreshment policies for web content caches" written in 2001, squid did not support. How about now? Thanks.
