nginx-0.1.16-RELEASE import *) 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.
