*) Bugfix: if the response were transferred by chunks, then on the HEAD
request the final chunk was issued.
*) Bugfix: the "Connection: keep-alive" header were issued, even if the
keepalive_timeout directive forbade the keep-alive use.
*) Bugfix: the errors in the ngx_http_fastcgi_module caused the
segmentation faults.
*) Bugfix: the compressed response encrypted by SSL may not transferred
complete.
*) Bugfix: the TCP-specific TCP_NODELAY, TCP_NOPSUH, and TCP_CORK
options, are not used for the unix domain sockets.
*) Feature: the rewrite directive supports the arguments rewriting.
*) Bugfix: the response code 400 was returned for the POST request with
the "Content-Length: 0" header; the bug had appeared in 0.1.14.
