htaccess子域名

Question

如何用htacess做到这一点:

subdomain.domain.com -> domain.com/subdomain (no redirect on client side)
domain.com/subdomain -> subdomain.domain.com (redirect)

我做冷杉重定向:

RewriteRule ^subdomain/ - [L]
RewriteCond %{HTTP_HOST} ^subdomain.domain.com [NC]
RewriteRule (.*) subdomain/$1 [L]

如何在htacess形式中插入:

AddDefaultCharset utf-8
DirectoryIndex index.php index.html index.htm
Options All -Indexes
ErrorDocument 404 /404.html
ErrorDocument 403 /404.html
RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]
RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|gif)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*)$  index.php/$1 [QSA]

Answer 1

这是一个基于通配符的解决方案,因此它适用于任意数量的子域.

这将重定向domain.com/foo/bar到foo.domain.com/bar:

RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule ([^/]+)(/.*|$) $1.domain.com/$2 [R=302]

这将处理(内部重写)虚拟主机:

RewriteCond %{HTTP_HOST} ^(.*).domain.com$ [NC]
RewriteRule (.*) %1/$1 [L]

您可以考虑使用301(永久重定向)而不是302.

我强烈建议VirtualHost您为主站点domain.com或www.domain.com提供一个用于处理虚拟子域的单独站点.

仅适用于某个子域:

RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule (subdomain)(/.*|$) $1.domain.com/$2 [R=302,L]

RewriteCond %{HTTP_HOST} ^(subdomain).domain.com$ [NC]
RewriteRule (.*) %1/$1 [L]
