Hello,
I use nginx server as a reverse proxy for a lot of diferent origins. Many virtualhosts with many upstream servers. I dont have total control of hostnames that will be configured on upstreams.This configuration will be done automatically based on what my clients configure on my solution CP. So I have some problems:

- One client can use invalid or wrong values, that does not resolver and put down all my server.
- I dont have control of hostname, if client make any change to the hostname or put down his dns server my nginx server can stop.
- If nginx cant contact my resolver all my soltion will go down

Use ip or hosts file is not a option because of environment variability.
I see this post http://forum.nginx.org/read.php?2,15995,16062 about the problem. I dont found any soltions for it.

Can that problem or behavior can be easy treaty by a patch? Nginx developer team have a roadmap or intent to change it? Can i pay for a patch that workaround this problem?

Thanks

Sky
