从非www重定向到www [英] redirect from non www to www

问题描述

我想将我的网站从example.com重定向到www.example.com

I want to redirect my site from example.com to www.example.com

推荐答案

Option 1: Redirecting example.com/dir/anypage.html to www.example.com/dir/anypage.html (same page)

Use this format if you want a request for any URL at example.com to redirect to the same page at www.example.com. (If you want to redirect to the home page of www.example.com, see option 2 below.)

    RewriteEngine On
    RewriteCond %{HTTP_HOST}  ^example.com [nocase]
    RewriteRule ^(.*)         http://www.example.com/

1 [last，redirect = 301]

1 [last,redirect=301]

Option 2: Redirecting example.com/dir/anypage.html to the www.example.com home page

Use this format if you want a request for any URL at example.com to redirect to the home page of www.example.com. (If you want to redirect to the same page at www.example.com, see option 1 above.)

    RewriteEngine On
    RewriteCond %{HTTP_HOST}  ^example.com [nocase]
    RewriteRule ^(.*)         http://www.example.com/ [last,redirect=301]

通过iis中的microsoft web platform安装程序安装url rewrite 2.0，并在Web配置文件中添加以下代码特定领域：

Install url rewrite 2.0 via microsoft web platform installer in your iis and add the following code in the web config file of particular domain:

<system.webserver>
    <rewrite>
      <rules>
        <rule name="Redirect domain.com to www" patternsyntax="Wildcard" stopprocessing="true">
          <match url="*" />
          <conditions logicalgrouping="MatchAny">
            <add input="{HTTP_HOST}" pattern="abc.com" />
            <add input="{HTTP_HOST}" pattern="ABC.COM" />
            <add input="{HTTP_HOST}" pattern="Abc.com" />
            <add input="{HTTP_HOST}" pattern="ABc.com" />
            <add input="{HTTP_HOST}" pattern="aBc.com" />
          </conditions>
          <action type="Redirect" url="http://www.abc.com/{R:0}" />
        </rule>
      </rules>
    </rewrite>
</system.webserver>
