Hi All, I would like to set up hierarchical caches with RAM only children and disk only parents.
Here is my setup as docker containers. https://github.com/hnakamur/ats-hierarchical-cache-experiment-docker/tree/ram_only_first_and_disk_only_second For the child server, I created the empty storage.config and set proxy.config.cache.ram_cache.size to 1048576 (1MB). However I got the following warning in the diags.log of the child cache. [Feb 16 05:55:25.535] Server {0x2ac07a601e40} WARNING: <Cache.cc:747 (start_internal)> unable to open cache disk(s): Cache Disabled For the parent server, I set proxy.config.cache.ram_cache.size to 0. However, I got the following via response header for the 4th request. https://github.com/hnakamur/ats-hierarchical-cache-experiment-docker/blob/ram_only_first_and_disk_only_second/README.md Via: http/1.1 copr-builder-883070330.novalocal (ApacheTrafficServer/6.1.1 [uScRs f p eN:t cCHi p s ]), http/1.1 copr-builder-883070330.novalocal (ApacheTrafficServer/6.1.1 [uScMsSf pSeN:t cCMi pSs ]) The left value (the parent cache) before the comma has c (cache-lookup) value "R", which is RAM hit. I don't know why a RAM hit occurs when I set proxy.config.cache.ram_cache.size to 0. How can I set up RAM only children and disk only parents? Is it possible? Best regards, Hioraki
