Untested, but I suggest you add a

upstream test.apphost.com { server 127.0.0.1:8080; }

and then make the following changes:

> location /server {
>
> proxy_pass http://127.0.0.1:8080/server;

change to

proxy_pass http://test.apphost.com;

> proxy_set_header Host $host;

Remove that.

> proxy_redirect off;

Remove that.

If you don't add the "upstream", then you should change

proxy_set_header Host $host;

to

proxy_set_header Host test.apphost.com;

because that is the Host: header that you say you want tomcat to get.

proxy_redirect (http://nginx.org/r/proxy_redirect) will rewrite a http
Location: response header, if it is given the chance.

The only place I think that this should fail, is if the tomcat service
returns http body content which refers to test.apphost.com. Ideally,
it shouldn't, or can be configured not to.

Good luck with it,
