Pointer #1 - ETag does mean cacheable. It is just a unique ID for the object. In an ideal HTTP world everything has an ETag to identify it, cacheable or not. And BTW just by using Squid everything gets stored. Whether its still usable next time the same URL is requested is another matter entirely. This is why Squid disk behaviour is mostly-write (2-5 objects written to disk for every 1 read back out). Pointer #2 - if your squid accepts the "ignore-no-cache" option then its too old. Upgrade to a squid-3.2+ which do HTTP/1.1 caching of no-cache/private/auth objects then work on it in the context of the newer versions extra capabilities.
