varnishd can use to decide if a backend state can be shared between multiple VCL programs. Originally the idea was to calculate a strong hash over the tokens which define the backend. Considering the relatively short lengths of backend declarations and the infrequency of comparisons, we have opted for an extremely weak hash instead: We simply output the space separted tokens as a string. The net change in code for simple backends is marginal, but for complex backends this will be a lot simpler to implement. git-svn-id: http://www.varnish-cache.org/svn/trunk/varnish-cache@2007 d4fa192b-c00b-0410-8231-f00ffab90ce4
