Nginx Reverse Proxy SSL / Minification

Nginx is the ideal solution for reverse-proxy, it's also Unix way "do one thing and do it well". So I'd advice you to split content serve and minification process out instead of using third-party plugins to do many things at once.

Best practice is to do minify&obfuscate phase on local system before you do a deployment on production, this is easy to say and not hard to do, see the google way to compress static assets. Once you got assets ready-to-use, we can setup nginx configuration.

Answers:

1. use minify&obfuscate before deploy it on production

2. you can find assets by regexp (directory name or file extension)

   location ~ ^/(assets|images|javascripts|stylesheets|swfs|system)/ { gzip_static on; expires max; add_header Cache-Control public; add_header Last-Modified ""; add_header ETag ""; break;}

3. use gzip on and gzip_static on to serve gzipped files instead of compress it every time when request is coming.

4. use try_files to detect the maintenance page exists or not

   try_files $uri /system/maintenance.html @mywebsite;

   if (-f $document_root/system/maintenance.html) { return 503;}

See the full nginx config for your case:
