comparison src/http/ngx_http_parse.c @ 28:7ca9bdc82b3f NGINX_0_1_14
nginx 0.1.14
*) Feature: the autoconfiguration directives:
--http-client-body-temp-path=PATH, --http-proxy-temp-path=PATH, and
--http-fastcgi-temp-path=PATH
*) Change: the directory name for the temporary files with the client
request body is specified by directive client_body_temp_path, by
default it is <prefix>/client_body_temp.
*) Feature: the ngx_http_fastcgi_module and the directives:
fastcgi_pass, fastcgi_root, fastcgi_index, fastcgi_params,
fastcgi_connect_timeout, fastcgi_send_timeout, fastcgi_read_timeout,
fastcgi_send_lowat, fastcgi_header_buffer_size, fastcgi_buffers,
fastcgi_busy_buffers_size, fastcgi_temp_path,
fastcgi_max_temp_file_size, fastcgi_temp_file_write_size,
fastcgi_next_upstream, and fastcgi_x_powered_by.
*) Bugfix: the "[alert] zero size buf" error; bug appeared in 0.1.3.
*) Change: the URI must be specified after the host name in the
proxy_pass directive.
*) Change: the %3F symbol in the URI was considered as the argument
string start.
*) Feature: the unix domain sockets support in the
ngx_http_proxy_module.
*) Feature: the ssl_engine and ssl_ciphers directives.
