= Varnish Cache Integration for Koala Framework

Adds support for Caching asset and media urls thru a varnish cache.

Those urls will use a different domain (varnish.domain). Proxying the whole page thru varnish is currently not supported.

== Installation

• add to config.ini:

  eventSubscribers.varnish = KwfVarnish_Events clearCacheTypes.varnishAssets = KwfVarnish_ClearCacheTypeAssets

• configure varnish.domain baseProperty:

  • one cdn domain: varnish.domain = cdn.example.com
  • multi domain web with different cdn domains: kwc.domains.com.varnish.domain = cdn.example.com
