You are right. My apache switched to different runtime user though it started as root. I changed the dir permission and atleast I can see some contents in the cache dir But now, I have hit another roadblock: Basically, I want the images to be served via cache and my images are distinguishable through query string http://backend-server.abc.com/mcs-stream-war/asset/streamAsset?id=e98a887b-2eb1-456d-ba18-d21a1b0b345th http://backend-server.abc.com/mcs-stream-war/asset/streamAsset?id=e98a887b-2eb1-456d-ba18-d21a1b0b456ft http://backend-server.abc.com/mcs-stream-war/asset/streamAsset?id=e98a887b-2eb1-456d-ba18-d21a1b023wert The problem is: Apache caching solution is ignoring whatever is there in the query string after ?. It means that whatever value I send in the query string, I am always served the first image. How can force apache caching solution to recognize the query strings and store images and its associated query string.
