Hello,  
I’m migrating an app from Apache/JBoss to nginx/Glassfish. I think I’m  
starting to grasp the server-location design but am getting errors when  
I try to proxy a request to Glassfish. Here’s a clip from my config:

server {  
server\_name [www.foobar.com](http://www.foobar.com) [foobar.com](http://foobar.com);  
root html/prod;  
index index.html;  
location /dc {  
proxy\_pass $scheme://localhost:8080$request\_uri;  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For  
$proxy\_add\_x\_forwarded\_for;  
proxy\_set\_header Host $http\_host;  
}  
}

The gist of it is I want all dynamic content (dc) to go to glassfish,  
i.e. [foobar.com/dc/somepath/page.jsp](http://foobar.com/dc/somepath/page.jsp)  
Everything else (presumably the static content) is served from  
html/prod. (That part works)  
I want the path to determine what happens, not the file extensions  
(because I have some .js that is static and other that is generated by  
the server).

I have a “hello world” app running on glassfish that works when accessed  
directly from localhost:8080/webtest/home,  
but when I try [foobar.com/dc/webtest/home](http://foobar.com/dc/webtest/home) I get a 502 Bad Gateway error  
in the browser. The nginx error log reports this:

2011/04/08 14:13:30 [notice] 3884#3940: signal process started  
2011/04/08 14:13:35 [error] 828#3472: \*6 no resolver defined to resolve  
localhost, client: 127.0.0.1, server: [www.foobar.com](http://www.foobar.com), request: “GET  
/dc/webtest/home HTTP/1.1”, host: “[foobar.com](http://foobar.com)”

Any ideas what might be wrong with my configuration?  
Thanks!  
Greg

- 

```
  proxy_pass $scheme://localhost:8080$request_uri;

```

- 

```
  proxy_pass http://localhost:8080;

```

Don’t use variables in proxy\_pass directive unless you really know  
why you need them and what it implies.

Ok, I changed that line to this:

```
  proxy_pass localhost:8080;

```

Still getting the same error unfortunately.

Because the http:// is required.

I believe it is not recommended to proxy to ssl backend (if possible at  
all).

Making progress! The /dc location wasn’t working because it wasn’t just  
rewriting the url, just proxying, so on my Glassfish server it was  
looking for /dc/…, which wasn’t there.

So for now I’ll just use location / and figure out another way to  
differentiate the dynamic and static content by location.  
At least now I can reach Glassfish from nginx, which is pretty cool.

Thanks for the lead!

One question, though… this didn’t work:

proxy\_pass localhost:8080;

This did:

proxy\_pass [http://localhost:8080](http://localhost:8080);

What if I want to proxy my ssl too?

You cannot “proxy SSL”, but you can setup a separate SSL connection to  
the backend.
