Hi,

in a reverse-proxy setup, what are the options to time the backend  
response…?  
There is no timing info in server-status.

Is the only way to get them to continually parse the logs for the  
$request\_time and/or $upstream\_response\_time (and optionally the  
$body\_bytes\_sent to calculate the size/time ratio)?

Thx,  
JD
