Dear Amos,

Can you please elaborate, I didnt understand. If possible can you explain with one example ? I mean behaviour of security and privacy flaws when 
strip_query_terms is on and when strip_query_terms is off.

If you are upgrading to a Squid with annotation support you can use an
external ACL helper to do the URL mangling you want for a custom log
%note column.
 Otherwise there is only that global on/off setting.


NP: stripping query-string is a very weak workaround for
security+privacy flaws. Any details hidden are being published elsewhere
anyway. All it does is prevent local detection of important information
leaks.
