Re: [squid-users] Why not cached ?

Hi babajaga,

You can add 'debug_options 20,9 27,9 31,9 70,9 82,9 22,9 84,9 90,9' to
your squid config to debug caching issues.
Search through log for string that contains 'NO' (in uppercase). This
string should explain why squid made decision not to cache http response.

Best wishes,
Pavel
