The Nginx binary you're using is not compiled with the ngx_srcache
module. See the Installation section in ngx_srcache module's
documentation here:

Thanks !! i built it correctly and its working.
I was wondering though, as to what is the best approach for my problem.

Problem:
serving images at high qps (4000-6000 qps).
Current approach. we user varnish-cache+ nginx backend. nginx backend serves the images from the
file-system. response times are really bad with the current approach.

The approach i have thought of is to have
nginx+memcached and back-end proxy will be nginx loading from file-system.

if image not present in memcached, load from backend, set into memcached with some expiry.

If some one can guide me with the pros and cons of this, it will be great...
