+===== Example: Reverse Proxy =====
+Nginx can function as a reverse proxy. This is particularly useful for:
+  * Accepting connections on secure standard ports and forwarding them to non-secure/standard ports for applications
+  * Sitting in front of an application server (that might be listening on localhost)
+  * Load balancing
+==== Forward to Non Standard Port ====
+This example accepts connections on standard port 443/tcp and forwards the request to a Java application listening on localhost, port 8080/tcp.
+<code bash>
+server {
+....
+# Location: Reverse Proxy to Java App
+    location /myapp/ {
+      # Forward /myapp/ requests to correct port
+      proxy_pass http://127.0.0.1:8080/myapp/;
+      # Additional headers to pass
+      proxy_set_header        Host            $host;
+      proxy_set_header        X-Real-IP       $remote_addr;
+      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
+    }
+}
