+# Nginx configuration example file
+
+This is a very common setup using an upstream. It was adapted from some Capistrano recipe I found on the Internet a while ago.
+
+```
+upstream myapp {
+ server unix:///myapp/tmp/puma.sock;
+}
+
+server {
+ listen 80;
+ server_name myapp.com;
+
+ # ~2 seconds is often enough for most folks to parse HTML/CSS and
+ # retrieve needed images/icons/frames, connections are cheap in
+ # nginx so increasing this is generally safe...
+ keepalive_timeout 5;
+
+ # path for static files
+ root /myapp/public;
+ access_log /myapp/log/nginx.access.log;
+ error_log /myapp/log/nginx.error.log info;
+
+ # this rewrites all the requests to the maintenance.html
+ # page if it exists in the doc root. This is for capistrano's
+ # disable web task
+ if (-f $document_root/maintenance.html) {
+ rewrite ^(.*)$ /maintenance.html last;
+ break;
+ }
+
+ location / {
+ proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+ proxy_set_header Host $http_host;
+
+ # If the file exists as a static file serve it directly without
+ # running all the other rewite tests on it
+ if (-f $request_filename) {
+ break;
+ }
+
+ # check for index.html for directory index
+ # if its there on the filesystem then rewite
+ # the url to add /index.html to the end of it
+ # and then break to send it to the next config rules.
+ if (-f $request_filename/index.html) {
+ rewrite (.*) $1/index.html break;
+ }
+
+ # this is the meat of the rack page caching config
+ # it adds .html to the end of the url and then checks
+ # the filesystem for that file. If it exists, then we
+ # rewite the url to have explicit .html on the end
+ # and then send it on its way to the next config rule.
+ # if there is no file on the fs then it sets all the
+ # necessary headers and proxies to our upstream mongrels
+ if (-f $request_filename.html) {
+ rewrite (.*) $1.html break;
+ }
+
+ if (!-f $request_filename) {
+ proxy_pass http://myapp;
+ break;
+ }
+ }
+
+ # Now this supposedly should work as it gets the filenames with querystrings that Rails provides.
+ # BUT there's a chance it could break the ajax calls.
+ location ~* \.(ico|css|gif|jpe?g|png)(\?[0-9]+)?$ {
+ expires max;
+ break;
+ }
+
+ location ~ ^/javascripts/.*\.js(\?[0-9]+)?$ {
+ expires max;
+ break;
+ }
+
+ # Error pages
+ # error_page 500 502 503 504 /500.html;
+ location = /500.html {
+ root /myapp/current/public;
+ }
+}
+```
