I have configures Nginx as reverse proxy/caching server to my apache webserver.
In the nginx config file I have setting of expires 30D at the server level. My apache config file has no expires directive , i mean no directive in the file. When I inspect my server response headers wchih seem to come from Nginx, I see the following for my http://www.example.com request:
**HTTP/200 responses are cacheable by default, unless Expires, Pragma, or Cache-Control headers are present and forbid caching. HTTP/1.0 Expires Header is present: Thu, 19 Nov 1981 08:52:00 GMT Legacy Pragma Header is present: no-cache
Can someone please suggest what is wrong , i want to set the expires to 1 month from now but it shows Thu, 19 Nov 1981 08:52:00 GMT.
Where should i start?
