Thanks Henrik for your answer, I know that lru does not take in account any size information. But my question is, even if not taking in account any size information, supposing to have two different cache_dir, one for big multimedia files and another one for small normal web doc, whenever squid needs space to cache a new web doc, for instance, will it even start the replacement policy on the cache_dir for big multimedia files, or only in the cache_dir for small web doc? Thanks in advance!
