Apache rewrite例子集合

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/{GetProperty(Content)} [R=permanent,L]
# Redirect webhosting-world.com to wbhw.com
RewriteCond %{REQUEST_URI} !^/forums/
RewriteRule /(.*) http://www.wbhw.com/{GetProperty(Content)} [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/{GetProperty(Content)} [R=permanent,L]
# Redirect webhosting-world.com to wbhw.com
RewriteCond %{REQUEST_URI} !^/forums/
RewriteRule /(.*) http://www.wbhw.com/{GetProperty(Content)} [R=permanent,L]
< /virtualhost>

URL重定向例子一:
1.http://www.zzz.com/xxx.php-&gt; http://www.zzz.com/xxx/
2.http://yyy.zzz.com-> http://www.zzz.com/user.php?username=yyy 的功能
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.zzz.com
RewriteCond %{REQUEST_URI} !^user\.php$
RewriteCond %{REQUEST_URI} \.php$
RewriteRule (.*)\.php$ http://www.zzz.com/{GetProperty(Content)}/ [R]
RewriteCond %{HTTP_HOST} !^www.zzz.com
RewriteRule ^(.+) %{HTTP_HOST} [C]
RewriteRule ^([^\.]+)\.zzz\.com http://www.zzz.com/user.php?username={GetProperty(Content)}
例子二：
/type.php?typeid=* --> /type*.html
/type.php?typeid=*&page=* --> /type*page*.html
RewriteRule ^/type([0-9]+).html$ /type.php?typeid={GetProperty(Content)} [PT]
RewriteRule ^/type([0-9]+)page([0-9]+).html$ /type.php?typeid={GetProperty(Content)}&page=$2 [PT]
