transferred while the 401 response code redirecting.

close a connection before anything was transferred to a client; bug
appeared in 0.1.38.
*) Workaround: the Linux glibc crypt_r() initialization bug.
*) Bugfix: the ngx_http_ssi_module did not support the relative URI in
the "include virtual" command.
*) Bugfix: if the backend response had the "Location" header line and
nginx should not rewrite this line, then the 500 code response body
was transferred; bug appeared in 0.1.29.
*) Bugfix: some directives of the ngx_http_proxy_module and
ngx_http_fastcgi_module were not inherited from the server to the
location level; bug appeared in 0.1.29.
*) Bugfix: the ngx_http_ssl_module did not support the certificate
chain.
