Hi.
I have one URL for all my websites, applications and so.
Let's say it's system.mydomain.com. Most of my websites is Apache + PHP and the applications is Tomcat. So far so good, no problem there.

My nginx config that's working for everything else:

server {
listen 80;
server_name system.mydomain.com;
....................
location /app1 {
return 301 https://$host$request_uri;
}
}
server {
listen 443 ssl;
server_name system.mydomain.com;
....................
location /app1 {
proxy_pass http://app1.mydomain.com;
}
}
upstream app1.mydomain.com {
server SERVER_IP_HERE:8081 fail_timeout=60;
}

Ok, my problem is when I have Alfresco for example on the backend. Alfresco responds on (fictional IP) "http://192.168.0.10/share".
I need to acess my nginx reverse proxy (another machine in front of Alfresco) on the URL: "http://system.mydomain.com/alfresco" and it should consume "http://192.168.0.10/share".
In my configuration above, the error is that when I acess "http://system.mydomain.com/alfresco" it will consume "http://192.168.0.10/alfresco".
How can I configure this to work? Rewrite?
