proxy_pass bug

[supeng]

I have a tomcat server  bind localhost:8080, and my nginx 0.8.24's conf is 
======================================
... ...

    server {
        listen       80;
        server_name  localhost;

        location / {
		proxy_pass http://localhost:8080;
	}
    }
... ...
======================================
when I access http://mydomain/docs, the url will be redirected to http://localhost/docs. Of course, the url, http://mydomain/docs/ , is working correctly!
