域名绑定子目录时隐藏路径的方法
一般我们在设置Hostmonster主机多域名绑定一个站点时，往往会在浏览器中出现子目录文件名。这样会让人们浏览到我们创建的子目录，如果我们不想让它出现，我们需要做一下转向设置，隐藏该子目录。首先需要在子目录中创建htaccess文件，然后上传以下代码：
Rewrite实现301转向
例如要将http://www.zhuohang.tk/bbs 转向到 http://bbs.zhuohang.tk 可以用： redirect 301 /bbs http://bbs.zhuohang.tk
或者
RewriteEngine On
RewriteRule ^(.*)$ http://bbs.zhuohang.tk/$1 [R=301,L]
上面的代码就可以将 http://www.zhuohang.tk/bbs/forum-51-1.html 这样类型的url转向到 http://bbs.zhuohang.tk/forum-51-1.html
补充说明：主域名指向子目录时使用以上方法不能实现隐藏子目录
理由：主域名绑定根目录，如果指向子目录需要设置转向功能。例如，使用以下代码进行设置：
RewriteEngine on
#更改yourmaindomain.com为你的主域名地址
RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$
# 更改主域名要指向的子目录
RewriteCond %{REQUEST_URI} !^/subfolder/
#不要更改这两行
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# 更改主域名要指向的子目录
RewriteRule ^(.*)$ /subfolder/$1
#更改yourmaindomain.com为你的主域名地址
RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$
#更改index.php为你的网站首页文件
RewriteRule ^(/)?$ subfolder/index.php [L]
在上述代码中实现了主域名指向子目录，使用了转向功能，如果再使用301转向设置隐藏子目录文件名。会造成循环转向。

替换 .htaccess 为 WordPress 提速
# BEGIN WordPress
RewriteEngine on
#
# Unless you have set a different RewriteBase preceding this
# point, you may delete or comment-out the following
# RewriteBase directive:
RewriteBase /
#
# if this request is for “/” or has already been rewritten to WP
RewriteCond $1 ^(index\.php)?$ [OR]
# or if request is for image, css, or js file
RewriteCond $1 \.(gif|jpg|css|js|ico)$ [NC,OR]
# or if URL resolves to existing file
RewriteCond %{REQUEST_FILENAME} -f [OR]
# or if URL resolves to existing directory
RewriteCond %{REQUEST_FILENAME} -d
# then skip the rewrite to WP
RewriteRule ^(.*)$ – [S=1]
# else rewrite the request to WP
RewriteRule . /index.php [L]
#
# END wordpress
