Hi !!! I installed squid on a Debian box, with 1Gb of RAM, 160 Gb of disk and AMD Optreon Dual Core, in transparent mode. I configured a cache of 100Gb on disk with aufs. I was making some testing in my private network, and I couldn't understand how the squid worked. I have this configuration: maximum_object_size 51200000 bytes minimum_object_size 0 bytes maximum_object_size_in_memory 204800 bytess When I send a HTTP requeriment for an object, for example of 1Kb, the object is saved by the squid "IN MEMORY" and the following requeriments from the same object, the squid answers with a "HIT" (This is ok) For the other side, when I send a request for an object bigger than 200Kb, it always resolves in "DIRECT" way and the following requeriments from the same object, the squid answer with a "MISS". The squid doesn't save this object on the disk cache, It's ok? May be I have a configuration problem. Any Help? Thanks a lot !!! Ramiro
