How to configure nginx for JBoss?

Is there a way to tell nginx which page to cache and how long to cache from an expressjs application running behind an nginx serving?

• Here nginx is serving as reverse proxy, and i don't want to play with nginx configuration , i just want to configure it dynmically from expressjs. I want to think it is possible by sending some specific headers like "Cache-Control" header. Expressjs is an example here, it may be any other application.

• Answer:

  You can add location directives in the config, putting specific configuration directives for specific URLs and URL patterns i.e. location /mystaticpage {   expires 1h;   add_header Cache-Control "max-age=3600"; } For the nginx itself to cache (using as http proxy) you can use in that location something like proxy_cache_valid 200 404 10m; that caches for 10 minutes what came with response code like 200 or 404 from that location.
