nginx-0.1.16-RELEASE importrelease-0.1.16

    *) 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.
