Dear list!

I’m new here, so I just hope I’m following the rules.

I would like to send a patch for http\_log\_module which I made for  
version nginx-1.0.10.

My company is in adserving business and it is important for us to log  
the big requests with the access\_log feature. But we were unable to do  
that with nginx, because logging all the requests would produce too much  
I/O load on our servers.

So I made a patch for http\_log\_module to accept a `size` parameter which  
is optional (the last parameter after the `buffer`). If this `size` is  
provided nginx logs only the big enough requests with access\_log (checks  
for `body_bytes_sent`).

I hope you find it useful and you will include this in the upstream.
