Thanks for the pointers and example config.
My target is to benchmark nginx, squid and varnish in their function as 
reverse proxy in front of slower backendservers running Apache, nginx or 
Reasons for using a rev.proxy are: general acceleration, avoid 
slash-dot-effects, added security, separation of tiers and better

That is, what I was wondering about, too; does NGINX do cache anything 
in default config? actually I doubt it.

Having a look at http://wiki.nginx.org/NginxHttpCoreModule tells us:
syntax: open_file_cache max = N [inactive = time] | off
default: open_file_cache off
context: http, server, location

OK, so there seem to be some caching-option, though they are not enabled 
by default.

Whereas the usage as proxy see 
offers a wide range of meaningful cache-configuration options.

One I like most (also avail in latest Squid-Versions) is 
"proxy_cache_use_stale" which basically allows you to 
shutdown/mantain/break the backendservers and still have the rev.proxy 
serve the Site to the public (from it's cache);

Sure, however this overhead by far outweights the benefits gained.

Interesting option, will look into it later;

I'd prefer to use the nginx-build-in cache rather than having it outside.

I hope to be able to present some comparisons be next week.
looking forward, regards georg
