Nginx 正则表达式匹配

Question

我有一个简单的要求，即向max-age除主页之外的所有页面添加标题。

location ~* ^/(.+)$ {
        add_header Cache-Control "public, max-age=86400";
        }

这个正则表达式应该可以工作，但是 Nginx 忽略了：

$ echo "/blog/pos1" | egrep "^/(.+)$" && echo "MATCH" || echo "NO MATCH"
/blog/pos1
MATCH
$ echo "/" | egrep "^/(.+)$" && echo "MATCH" || echo "NO MATCH"
NO MATCH
$ echo "" | egrep "^/(.+)$" && echo "MATCH" || echo "NO MATCH"
NO MATCH

配置：

server {

    listen      80;
    root        /var/www/html/test;
    index index.php index.html index.htm;
    server_name tmp.local;

    location = /favicon.ico {
    return 204;
    }


location ~ ^/. {
        expires 86400s;
        }


location ~ \.php$ {
    fastcgi_pass unix:/var/run/php-fpm/www.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
    }

    location ~ /\. {
    access_log off;
    log_not_found off;
    deny  all;
    }

location ~* \.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|flv|mp3)$ {
    access_log off;
    log_not_found off;
    expires 1209600s;
    add_header X-Frame-Options "DENY";
    }
}
