annotate src/http/modules/ngx_http_charset_filter_module.c @ 663:6d5c1535bb9d release-0.3.53
nginx-0.3.53-RELEASE import
*) Change: the "add_header" directive adds the string to 204, 301, and
302 responses.
*) Feature: the "server" directive in the "upstream" context supports
the "weight" parameter.
*) Feature: the "server_name" directive supports the "*" wildcard.
*) Feature: nginx supports the request body size more than 2G.
*) Bugfix: if a client was successfully authorized using "satisfy_any
on", then anyway the message "access forbidden by rule" was written
in the log.
*) Bugfix: the "PUT" method may erroneously not create a file and
return the 409 code.
*) Bugfix: if the IMAP/POP3 backend returned an error, then nginx
continued proxying anyway.
