How to use Glassfish under Linux as a reverse-proxy

Any redirect to localhost doesn't make sense from a remote system (e.g. client's Web browser). So the rewrite flags permanent (301) or redirect (302) are not usable in your case.

Please try following setup using a transparent rewrite rule:

location  /foo {
  rewrite /foo/(.*) /$1  break;
  proxy_pass         http://localhost:3200;
  proxy_redirect     off;
  proxy_set_header   Host $host;
}

Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect.

If I understand you correctly, which I'm not sure I do to be honest, then yes you can.

You don't mention how you are doing the reverse proxying, but if you are not already doing so, my advice would be to use mod re-write.

Imaging you have the following: Internal server called private.mydomain.com, which hosts an app, lets call it myApp, that you want to make available to the public via your world-facing web server. This app is at http://private.mydomain.com/myapp.

Your public server is called www, and you want to make the app visible to the world at www.mydomain.com/myapp

You would use Modrewrite on the public server something like this:

RewriteEngine        on
RewriteRule ^/myapp(.*) http://private.mydomain/com/myapp$1 [P,L]

(if you want to reverse proxy HTTPS URLs you also need SSLProxyEngine On)
