  ##        CHUNKED TRANSFER      ##
  ##################################
  ##
  ## It is a known issue that Git-over-HTTP requires chunked transfer encoding [0]
  ## which is not supported by Nginx < 1.3.9 [1]. As a result, pushing a large object
  ## with Git (i.e. a single large file) can lead to a 411 error. In theory you can get
  ## around this by tweaking this configuration file and either:
  ## - installing an old version of Nginx with the chunkin module [2] compiled in, or
  ## - using a newer version of Nginx.
  ##
  ## At the time of writing we do not know if either of these theoretical solutions works.
  ## As a workaround users can use Git over SSH to push large files.
