- refreshing traffic going through refresh_patterns
The original concept and first version of Squeezer appeared
in 1999, when I was working at Nicolas Copernicus University
in Toruń, Poland. I needed a tool to show that Squid really
speeds up web access. I also wanted to find "bottlenecks"
and tweak Squid's configuration. I have written tool "after
hours" on my own. I also wrote a guide about configuring
Squid for optimizing performance. It
is available on Web
and also discussed in
Polish IT magazine PCkurier
and 2000.Apache.con conference.
Soon after creating Squeezer I left NCU and also left web
caching for years. In 2003
Andrew Fresh rewrote Squeezer.
Andrew's work (e.g. programming style, data structures) and
interest from other people inspired me to rewrite Squeezer
again. It is now updated to work with current Squid logs.
The programming style has been improved to easier
maintenance and further development.
