Hi, As of now, we can not make requests without having actual connection(conn_rec) to the server.
For example, mod-cache-requester needs to make request for popular and soon-to-expire from cache pages so that these pages are reloaded in the cache. right now, it has to rely on libcurl to re-request page, which is not very elegant. other than mod-cache-requester, There are many other intersting things that can be done if we could create requests internally without requiring conn_rec. I looked over existing code, It seems, the best (and easiest) way to implement this is by mocking up conn_rec. so basically we implement one more version of core_create_conn() function which would initialize request url, sockets and various pools such that this conn_rec would work with existing request_rec. we can pass this mocked up conn_rec to make_sub_request and thus would be bale to make requests internally. any thoughts? I believe, apr_http_client would solve this problem, but I am not sure about the status of it. If anybody is working on it and dont mind if I jump into the development cycle, let me know. I would love to get my hands dirty in this problem. -Parin.
