I am sure there is a better way but here is a suggestion. Use the rate
limit to identify when there is more than one connection per minute and
redirect that to the cache, if it doesnt hit that limit then you can use the
cache_bypass. Not sure if this would work hope someone can confirm, but a
thought.

limit_req_zone $binary_remote_addr zone=one:10m rate=1r/m;
location / {

limit_req zone=one burst=1 nodelay;
error_page 503 = @cached;
set $http_my_secret_header "0"; proxy_cache_bypass $http_my_secret_header;

location @cached {

proxy_pass
}
