Probably https://docs.trafficserver.apache.org/developer-guide/cache-architecture/architecture.en.html would be what you are looking for. > The docs of ATS does not introduce how the disk cache admits and evicts objects. - Think of the disk cache as a circular buffer. Roughly, as it gets objects to cache, it writes it at the current spot on the circle. Eg, once the disk is full, a new object will overwrite an existing one. (There is a setting to help keep frequent accessed docs in cache -- if a requested object is about to be overwritten, it can be kept.) > Also, When an object is received, how ATS decides whether the disk or the RAM caches it? Are the two type of cache work independently? First an object is written to disk cache. If it's seen frequently enough, it gets promoted to RAM cache. -- This is an automated message from the Apache Git Service.
