Varnish + Tomcat vs Apache + mod_cache + mod_jk +Tomcat

[Adrian Ber]

Definitely VCL is easier to use than Apache config. And Varnish/Apache and Tomcat will be sitting on the same (cloud) machine.
Then practically I would be interested in a comparison of the overhead added by Apache vs Varnish in terms of non-cached requests.

Thanks,
Adrian.
