annotate src/http/modules/ngx_http_charset_filter_module.c @ 667:63a820b0bc6c release-0.3.55
nginx-0.3.55-RELEASE import
*) Feature: the "stub" parameter in the "include" SSI command.
*) Feature: the "block" SSI command.
*) Feature: the unicode2nginx script was added to contrib.
*) Bugfix: if a "root" was specified by variable only, then the root
was relative to a server prefix.
*) Bugfix: if the request contained "//" or "/./" and escaped symbols
after them, then the proxied request was sent unescaped.
*) Bugfix: the $r->headers_in("Cookie") of the ngx_http_perl_module now
returns all "Cookie" header lines.
*) Bugfix: a segmentation fault occurred if
"client_body_in_file_only on" was used and nginx switched to a next
upstream.
*) Bugfix: on some condition while reconfiguration character codes
inside the "charset_map" may be treated invalid; the bug had
appeared in 0.3.50.
