需要特别留意下,apache的配置是有顺序关系的,以下为先后:

1. <Directory> (except regular expressions) and .htaccess done simultaneously (with .htaccess, if allowed, overriding <Directory>)
2. <DirectoryMatch> (and <Directory ~>)
3. <Files> and <FilesMatch> done simultaneously
4. <Location> and <LocationMatch> done simultaneously

举个例子,执行顺序是 A > B > C > D > E

<Location />
E
</Location>

<Files f.html>
D
</Files>

<VirtualHost *>
<Directory /a/b>
B
</Directory>
</VirtualHost>

<DirectoryMatch “^.*b/”>
C
</DirectoryMatch>

<Directory /a/b>
A
</Directory>

一个危险的示例,在这个例子里边,其实deny 不生效,因为被后生效的 location 配置覆盖了

<Location />
Order deny,allow
Allow from all
</Location>

# Woops! This <Directory> section will have no effect
<Directory />
Order allow,deny
Allow from all
Deny from badguy.example.com
</Directory>
