Mod Rewrite 吾铺行政在 httpd 中将一个域名转发到另一个域名
虚拟主机世界近期更换了域名，新域名为 www.wbhw.com, 更加简短好记。这时需要将原来的域名 webhosting-world.com, 以及论坛所在地址 webhosting-world.com/forums/ 定向到新的域名，以便用户可以找到，并且使原来的论坛 URL 继续有效而不出现 404 未找到，比如原来的 http://www. webhosting-world.com/forums/-f60.html, 让它在新的域名下继续有效，点击后转发到 http://bbs.wbhw.com/-f60.html, 这就需要用 apache 的 Mod_rewrite 功能来实现。
在< virtualhost> 中添加下面的重定向规则：
RewriteEngine On
# Redirect webhosting-world.com/forums to bbs.wbhw.com
RewriteCond %{REQUEST_URI} ^/forums/
RewriteRule /forums/(.*) http://bbs.wbhw.com/$1 [R=permanent,L]
# Redirect webhosting-world.com to wbhw.com
RewriteCond %{REQUEST_URI} !^/forums/
RewriteRule /(.*) http://www.wbhw.com/$1 [R=permanent,L]
添加了上面的规则以后， 里的全部内容如下：
< virtualhost *:80>
ServerAlias webhosting-world.com
ServerAdmin admin@webhosting-world.com
DocumentRoot /path/to/webhosting-world/root
ServerName www.webhosting-world.com
RewriteEngine On
# Redirect webhosting-world.com/forums to bbs.wbhw.com
RewriteCond %{REQUEST_URI} ^/forums/
RewriteRule /forums/(.*) http://bbs.wbhw.com/$1 [R=permanent,L]
# Redirect webhosting-world.com to wbhw.com
RewriteCond %{REQUEST_URI} !^/forums/
RewriteRule /(.*) http://www.wbhw.com/$1 [R=permanent,L]
< /virtualhost>
