Hi, I'm trying to implement this style of proxy_cache config http://fennb.com/microcaching-speed-your-app-up-250x-with-no-n as a test locally, to stick in front of php sites. This is what I have: http://pastie.org/2703119 http://local-nocache.domain.co.uk works as expected, but http://local.domain.co.uk gives me a 502. Grateful for any advice. thanks, Jon
