FastCGI: combining headers with identical names (ticket #1724).

2022-05-30T18:25:27+00:00

FastCGI responder is expected to receive CGI/1.1 environment variables
in the parameters (see section "6.2 Responder" of the FastCGI specification).
Obviously enough, there cannot be multiple environment variables with
the same name.

Further, CGI specification (RFC 3875, section "4.1.18. Protocol-Specific
Meta-Variables") explicitly requires to combine headers: "If multiple
header fields with the same field-name are received then the server MUST
rewrite them as a single value having the same semantics".

    *) Feature: the "proxy_hide_header", "proxy_pass_header",
       "fastcgi_hide_header", and "fastcgi_pass_header" directives.

    *) Change: the "proxy_pass_x_powered_by", "fastcgi_x_powered_by", and
       "proxy_pass_server" directives were canceled.

    *) Feature: the "X-Accel-Buffering" response header line is supported
       in proxy mode.

    *) Bugfix: the reconfiguration bug and memory leaks in the
       ngx_http_perl_module.

    *) Bugfix: in SSI handling.

    *) Bugfix: the ngx_http_memcached_module did not support the keys in

nginx-0.3.18-RELEASE import

2005-12-26T17:07:48+00:00

    *) Feature: the "server_names" directive supports the ".domain.tld"
       names.

    *) Feature: the "server_names" directive uses the hash for the
       "*.domain.tld" names and more effective hash for usual names.

    *) Change: the "server_names_hash_max_size" and
       "server_names_hash_bucket_size" directives.

    *) Change: the "server_names_hash" and "server_names_hash_threshold"
       directives were canceled.

    *) Feature: the "valid_referers" directive uses the hash site names.

    *) Change: now the "valid_referers" directive checks the site names
       only without the URI part.

    *) Bugfix: some ".domain.tld" names incorrectly processed by the
       ngx_http_map_module.

    *) Bugfix: segmentation fault was occurred if configuration file did
       not exist; the bug had appeared in 0.3.12.

    *) Bugfix: on 64-bit platforms segmentation fault may occurred on
       start; the bug had appeared in 0.3.16.

    *) Feature: the "worker_rlimit_core" directive.

    *) Workaround: the connection number in logs was always 1 if nginx was
       built by the icc 8.1 or 9.0 compilers with optimization for
       Pentium 4.

    *) Bugfix: the "config timefmt" SSI command set incorrect time format.

    *) Bugfix: nginx did not close connection to IMAP/POP3 backend for the
       SSL connections; the bug had appeared in 0.3.13.
