Tomcat, domains and Nginx

Hello,

I have some web apps on my tomcat server
And i have some domains name.


I would like to redirect domain on it web app.


If i'm using

location /app {
proxy_pass http://host/app ;
}

My app works fine


But if i'm using


location / {
proxy_pass http://host/app ;
}


I'm redirecting to
http://host/app/app

And my app does not working.


I have tried to use
proxy_redirect http://host/app /;

and subs_filter

But i have the same problem.


How can i redirect www.mydomain.com to http://tomcat/my_app
and not
http://tomcat/my_app/my_app


My vhost :



server {
listen 80; ## listen for ipv4
server_name mydomain.com;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log debug;

location / {
index index.jsp;
proxy_pass http://proxy/myapp ;
}
}


proxy :

upstream proxy {
sticky name=proxy;
server serveur_ip1:8080;
server serveur_ip2:8080;
}
