I am having a proxy issue that seems to be a java problem…

We have a config that listens on port 10000 https and then proxies https  
to the backend on port 443. This works fine until I try and bring up a  
java applet which promptly tries to connect to port 443 instead of  
10000. Is there a way to rewrite the information the backend is sending  
to the java  
applet to make it connect to port 10000 instead of 443?

Thanks

If this is caused by redirect returned by backend, then try

[http://wiki.codemongers.com/NginxHttpProxyModule#proxy\_redirect](http://wiki.codemongers.com/NginxHttpProxyModule#proxy_redirect)

proxy\_redirect [https://backend/](https://backend/)[https://frontend:10000/](https://frontend:10000/);

or simply

proxy\_redirect [https://backend/](https://backend/) /;

But the nginx is only listening on port 10000 , not 443, the backend  
sends some URL for the java applet that makes it  
connect to 443 instead of 10000 … I’m trying to figure out what that  
is… Will this intercept something from the backend?

Right now I have it set up like this:  
server  
{  
listen 1.1.1.1:10000;  
ssl on;  
ssl\_certificate  
/usr/local/nginx/conf/abc.crt;  
ssl\_certificate\_key  
/usr/local/nginx/conf/abc.key;  
location /  
{  
proxy\_pass [https://10.150.42.112](https://10.150.42.112);  
proxy\_redirect [https://10.150.42.112/](https://10.150.42.112/)  
https://$http\_host/;  
proxy\_redirect default;  
}  
}
