I am trying to diagnose a weird 408 error problem on nginx.
My theory is that the client might be using some kind of crack making
request body too short for Content-Length header, so nginx waits more
and ultimately fails at 60 seconds timeout.
I tried to add few more log options, like $content_length and
$request_length, however, the $request_length includes all the header
body length, thus can not get actuall body length.
Does nginx provide variables like $request_header_length and
Thanks in advance!
