We face an issue that `http.current_active_client_connections` metrics keep increasing. After investigation with @cmcfarlen and @moonchen, we found `HttpSM` hangs on `state_cache_open_read` when it follows redirect and `HttpCacheSM::captive_action` was cancelled. Because `HttpCacheSM::state_cache_open_read` does nothing. https://github.com/apache/trafficserver/blob/b1e9327069fde8207c2d5ed6178addc4e237498e/src/proxy/http/HttpCacheSM.cc#L106-L112 To fix the issue, this PR does reset `captive_action.cancelled` and other counters of `HttpCacheSM` on following redirect. From our testing, this patch seems working, however, `captive_action` and `pending_action` related code seems pretty odd. They should be fixed. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
