Hi,

I'm using nginx-1.2.0 and I'm really happy with that. However I want to add a couple of Headers ($upstream_response_time in this case) to be passed to the Client for debugging purposes. So I've added `add_header X-AppServer-Response $upstream_response_time;` to my location block where I do all my proxy stuff. I've got an upstream block where I've put in my 3 backend servers. All Backends respond very fast during testing.

However there are unreasonable high values within this header (X-AppServer-Response: 74768.562 in this case). I'm using access_log to get some more values written to disk as well for central monitoring. Within this log all values seem to be ok (for this particular request it's 0.002 to be exact). I was able to reproduce this on different platforms using different browsers.

Any Idea what's going wrong here?

Regards,
Chris
