: with the index being a few minutes stale as the TTL expires on the cache. I : don't think solr has a way to, at query time, change the cache control : headers.
SolrJ lets the HttpClient instance handle all network connections, so specify whatever caching/proxy info you want to it, and then pass it to your CommonsHttpSolrServer constructor. you should be able to easily a new CommonsHttpSolrServer for each request (they're pretty cheap to construct) or have N CommonsHttpSolrServer each with a different HttpClient instance for supporting N different caching/proxying prefrences (just pick which CommonsHttpSolrServer to use on each request depending on what behavior you want) -Hoss
