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
the
request body too short for Content-Length header, so nginx waits more
data
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
and
body length, thus can not get actuall body length.
Does nginx provide variables like $request_header_length and
$request_body_length?
