Re: [squid-users] flat file parsing vs db filter rules parsing

Hello Hendrik,

    Thanks for detailed explanation. I need some more queries as inlined as,

Can you prefer, which ACL types are being used as flat file parsing based and DB filter rules parsing based. How are the parsing of
filter rules are differed in implementation. All configurations are parsed from squid.conf flat file there. where are we using logic
of db based parsing on squid.?

I heard Performance and parsing time using db based are fast. Can we adopt db based filter rules parsing on squid-2.5 series without
using any redirectors there. How the squid-3.0 adaptation will be differed from now?

Can you prefer, how we can know filter rules parsing with flat files or db based conceptually? We are on-going with source files of
squid's *cf* .c and .h files. We are on the analysis to improve squid filter rules parsing and filter adapation.

Thanks for your information and time.

Muthukumar.
