I'm trying to write a rule to proxy /varz requests to all my backends for a production dashboard. I'd like to specify the host and port in the request URL. Here's what I've tried, but I get a 502 Bad Gateway from nginx.

[code]
location /dashboard/varz {
if ($args ~ "host=([a-z0-9]*)&port=([0-9]*)") {
set $varz_host $1;
set $varz_port $2;
proxy_pass http://$varz_host.mydomain.com:$varz_port/varz;
}
proxy_redirect off;
...
}
[/code]

I'm running nginx/0.6.36. Any other suggestions?

Thanks,
Jared

Hi

I don't know how you could do what you are intending to do. But are you aware of that you would create an open proxy if you put that out into the wild?

Yes, I'm aware. The dashboard requires authentication (note the "..."). Thanks.
