Nginx how to completly disable Proxy caching

Question

For what i understand proxy_cache can only be disable by changing the incoming request headers to somtehing like Cache-Control': 'no-cache'. This seems to not be working for me, is there any way to completly disble caching for that proxy ?

proxy_cache off didn t work either response headers always come back like that:

Cache-Control max-age=86400

Connection keep-alive

Content-Type text/plain

Date Mon, 19 Mar 2012 19:42:28 GMT

Expires Tue, 20 Mar 2012 19:42:28 GMT

Server nginx/0.7.65

Transfer-Encoding chunked

Aldo the request i am proxing are comming from node.js server so i need to enable "streaming"

Thanks
