         实现123.com全部重定向 (跳转)到www.123.com。同时按照google的建议,使用服务器端 301 重定向,为了确保用户及搜索引擎定向至正确网页的最佳方法。301 状态代码表示某网页已被永久迁移至新位置。下面将了解一下apache下实现301永久性重定向2个方法,需要具有访问服务器的 .htaccess 文件的权限。



 

1. Apache模块 mod_alias的 Redirect 和 RedirectMatch命令

上面提到2个命令使用方法相似。而区别就是后者RedirectMatch基于正则表达式匹配对当前的URL发送一个外部重定向语法为:

Redirect [status] URL-path URL

RedirectMatch [status] regex URL

status参数可以使用以下HTTP状态码:

permanent

返回一个永久性重定向状态码(301),表示此资源的位置变动是永久性的。

temp

返回一个临时性重定向状态码(302),这是默认值。

seeother

返回一个“参见”状态码(303),表示此资源已经被替代。

gone

返回一个“已废弃”状态码(410),表示此资源已经被永久性地删除了。如果指定了这个状态码,则URL参数将被忽略。

举例:

APACHE

Redirect 301 /old/old.htm http://www.123.com/new.htm
Redirect permanent /one http://123.com/two
RedirectMatch 301 (.*).gif$ http://www.123.com/images/$1.jpg


2.使用mod_rewrite重写URL方式

APACHE

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^123.com
RewriteRule ^(.*)$ http://www.123.com/$1 [R=permanent,L]


在这里判断当前服务器变量HTTP_HOST是否等于1230.com,为真就进行重写,按照R=permanent进行永久重定向,L表示并立即停止重写操作,并不再应用其他重写规则

下面是apache最终实现的.htaccess文件,同时也并入ecshop重写规则。
