nginx默认未编译此模块；让nginx编译启用此模块

./configure --prefix=/data/web --sbin-path=/usr/bin --user=nginx --group=nginx --with-http_stub_status_module --with-http_auth_request_module --with-http_sub_module --add-module=/root/nginx-http-concat --with-http_addition_module makemv /usr/bin/nginx{,.07.12.13.18} cp objs/nginx /usr/bin/

addition指令介绍

Syntax: add_before_body uri; #在body之前添加，添加的内容就是后面的uri,让nginx去访问这个uri获取资源，根户请求返回的添加待body之前Default: —Context: http, server, locationSyntax: add_after_body uri;  # 在body之后添加Default: —Context: http, server, locationSyntax: addition_types mime-type ...;  #那些资源类型的请求可以使用Default: addition_types text/html; Context: http, server, location

　　配置不启用时；配置

[root@python vhast]# cat addition.conf server {	server_name addition.com;	access_log logs/addition.log main;	location / {		#add_before_body /before_action;		#add_after_body /after_action;		#addition_types *;	}	location /before_action {		return 200 'new centos before_action\n';	}	location /after_action {		return 200 'new centos after_action\n';	}}

　　测试

[root@python vhast]# curl addition.comWelcome to nginx!
