2 其它acl 规则
1. ###########acl 开始了############
2. acl bbs hdr_reg(host) -i ^(bbs.test.com|forum.test.com)#使用正则匹配
3. acl bbs_pathpath_beg -i /bbs #url 目录
4. acl youxi path_beg -i /youxi
5. acl static path_end -i .html .css .js #url 结尾文件
6. acl php path_end -i .php
7. acl jsp path_end -i .jsp .do
8.
9. use_backend bbs_pool if bbs or bbs_path #注意 "or"
10.use_backend youxi_pool if youxi
11.use_backend static_pool if static
12.use_backend php_pool if php
13.use_backend jsp_pool if jsp
14.default_backend www.test.com
15.###########acl 结束了############
#acl 参数
acl(关键字) 定义acl(名称)方法 -i (忽略大小写) [匹配的路径或文件]
hdr_beg(host)
hdr_reg(host)
path_beg
path_end
3 use_backend 参数
1. or 用于匹配多个acl 名称
2. default_backend 没有满足条件的时候使用默认的后端服务器
