Get the lastest nginx (0.7.50) and use

    proxy_cache_path  /path/to/cache  levels=1:2
                      keys_zone=one:10m
                      inactive=7d  max_size=200m;

    proxy_temp_path   /path/to/temp;  # must be on the same filesystem
                                      # as cache

    server {

        location / {
            proxy_pass              http://backend;

            proxy_cache             one;
            proxy_cache_key         backend$request_uri;
            proxy_cache_valid       200  1h;
            proxy_cache_use_stale   error timeout invalid_header;
        }
