Hi  
I would like to log an indication of weather a request ended because of  
a client timeout - in the access.log

e.g.

log\_format normal '$remote\_addr - $remote\_user [$time\_local] ’  
'"$request" $status $bytes\_sent ’ ‘"$http\_referer" “$http\_user\_agent”  
“$client\_send\_timed\_out”’;  
where $client\_send\_timed\_out would be a true/false or an 0/1 etc

Is there anything in there that would allow me to log that?

Many thanks  
Richard

Closest to what you ask about I can think of is the  
$request\_completion variable. Though it marks not only timeouts  
but whether a request was completely served or not.

[http://nginx.org/en/docs/http/ngx\_http\_core\_module.html#var\_request\_completion](http://nginx.org/en/docs/http/ngx_http_core_module.html#var_request_completion)

thanks that might be what I need (as long as I ignore mp4/flv seeking  
requests)

Cheers
