It's a filter defining how detailed debug messages may be printed on
stdout. Normally debug messages only go into cache.log.

-d in itself do not enable any extra debugging, just enables them to be
printed on stdout if enabled.

You define the current debug level using "debug_options" in squid.conf,
or toggle full debugging on/off using "squid -k debug".

You can find the debug sections in doc/debug-sections.txt, and you can
set the debug level individually for each section, where level 0 is only
critical messages and 9 is full debugging (higher numbers is also
supported, but do not increase the amount of debugging shown)

When I am debugging Squid I usually use the following command line
options: -DNYCd3, and toggle debugging on/off using "squid -k debug"
when needed. -d3 usually gives sufficient messages on stdout to
understand what is going on when debugging is enabled, and one can
always look into cache.log to see all the debug messages.

For production use you typically do not use any -d option at all, or
perhaps -d0.
