Note that Expires and Last-Modified are the same, and X-ExecutionTime headers match exactly: HTTP/1.1 200 OK Server: nginx/1.2.7 Date: Sun, 03 Mar 2013 12:49:14 GMT Content-Type: text/html; charset=utf-8 Content-Length: 10727 Connection: close X-AspNetMvc-Version: 4.0 X-ExecutionTime: 00:00:00.1373919 X-ExecutionTime: 00:00:00.1717868 X-AspNet-Version: 4.0.30319 Expires: Sun, 3 Mar 2013 13:22:27 GMT Cache-Control: public, max-age=3600 Last-Modified: Sun, 3 Mar 2013 12:22:27 GMT X-Cache: MISS HTTP/1.1 200 OK Server: nginx/1.2.7 Date: Sun, 03 Mar 2013 12:49:31 GMT Content-Type: text/html; charset=utf-8 Content-Length: 10727 Connection: close X-AspNetMvc-Version: 4.0 X-ExecutionTime: 00:00:00.1373919 X-ExecutionTime: 00:00:00.1717868 X-AspNet-Version: 4.0.30319 Expires: Sun, 3 Mar 2013 13:22:27 GMT Cache-Control: public, max-age=3600 Last-Modified: Sun, 3 Mar 2013 12:22:27 GMT X-Cache: MISS HTTP/1.1 200 OK Server: nginx/1.2.7 Date: Sun, 03 Mar 2013 12:50:25 GMT Content-Type: text/html; charset=utf-8 Content-Length: 10727 Connection: close X-AspNetMvc-Version: 4.0 X-ExecutionTime: 00:00:00.1373919 X-ExecutionTime: 00:00:00.1717868 X-AspNet-Version: 4.0.30319 Expires: Sun, 3 Mar 2013 13:22:27 GMT Cache-Control: public, max-age=3600 Last-Modified: Sun, 3 Mar 2013 12:22:27 GMT X-Cache: MISS -- Maxim Dounin http://nginx.org/en/donation.html _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
