Varnish cache，或称Varnish，是一套高效能的反向网站快取服务器（reverse proxy server）。
Varnish目前被用在挪威最大的报社Verdens Gang上。此版本是varnish 3.0 分支第二个beta测试版，主要是一些bug的修复和改进。不出意外的话，3.0正式版将会在下个月发布。下载：http://repo.varnish-cache.org/source/varnish-3.0.0-beta2.tar.gz

较前一版本beta 1的主要改进:

* documentation updates, particularly for the standard VMOD.

* varnishncsa now ignores piped requests, since there's generally too
little information for us to do anything sensible with them.

* the VCL compiler is now stricter in enforcing no duplication of
backends or probes.

* the «stats» command has been removed from the CLI interface as it did
not work well with the new dynamic counters.

* VCL now has vcl_init and vcl_fini functions that are called when a
VCL is loaded or unloaded. This can be used for initialising VMODs.
