simple and nice

Spend few hours to get Plone running behind Nginx through proxy_pass. It supposed to be as simple as:-

server {
    listen      80;
    server_name cvt.int-prokab.com;
    root html;

    rewrite ^/(.*)$ /cvt last;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header        Host            $host;
        proxy_set_header        X-Real-IP       $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

The plone site are running on port 8080 at 127.0.0.1:8080/cvt. I want it to be exposed to the outside as http://cvt.int-prokab.com/ but it turn out that Plone generate all url on the site as 127.0.0.1:8080/cvt - the address behind and not the exposed public url. Reading explanation on ZMI Virtual Hosting interface:-

The VHM doesn’t do anything unless it sees one of the following special path elements in a URL: VirtualHostBase sets the protocol and host, while VirtualHostRoot sets the path root. If the URL path of a request begins with ”/VirtualHostBase/http/www.buystuff.com”, for instance, then URLs generated by Zope will start with http://www.buystuff.com. Since the port number was not specified, it is left unchanged. If your Zope is running on port 8080, and you want generated URLs not to include this port number, you must use ”/VirtualHostBase/http/www.buystuff.com:80”. If the URL contains VirtualHostRoot, then all path elements up to that point are removed from generated URLs. For instance, a request with path ”/a/b/c/VirtualHostRoot/d” will traverse “a/b/c/d” and then generate a URL with path /d.

Took me sometimes and hair pulling before I could understand how it would work. The rewrite supposed to be like this:-

rewrite ^/(.*)$ /VirtualHostBase/http/cvt.int-prokab.com:80/cvt/VirtualHostRoot/$1 last;
