具有动态域名的.htaccess www -重定向(R301)

Question

我想重定向3级或4级域以添加“www”：

DirectoryIndex index.php

RewriteEngine on
RewriteRule ^$ /home/ [R=301,L]


RewriteRule ^(?!www[\.]) http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?p=/$1 [QSA] 

我的问题是这可能是一个不同的水平..。www。froschkoenig84。放好了。net。froschkoenig84。de

所以当它不是以“www”开头的时候。那就加一句，否则.

RewriteRule ^(？) http://www.%{HTTP_HOST}%{REQUEST_URI} R=301，L

但不起作用..。它每次都在增加..。所以结局就像..。

​

我怎样才能检查它是否以“www”开头。还是不想？如果可能的话，那就没有单独的条件。:)

我还为.NET (web.config)创建了类似的重写规则：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 <system.webServer>
  <rewrite>
   <rules>
    <rule name="RedirectToHome" stopProcessing="true">
     <match url="^$" />
     <conditions trackAllCaptures="true">
      <add input="{CACHE_URL}" pattern="^(https?)://" />
     </conditions>
     <action type="Redirect" redirectType="Permanent" url="{ToLower:{C:1}://{HTTP_HOST}/home/}" />
    </rule>
    <rule name="RedirectToWWW" stopProcessing="true">
     <match url="(.*)" ignoreCase="false"  />
     <conditions>
      <add input="{CACHE_URL}" pattern="^(https?://)(?!www[\.])" />
     </conditions>
     <action type="Redirect" url="{ToLower:{C:1}www[\.]{R:1}}" redirectType="Permanent" />
    </rule>
    <rule name="RewriteToParams" stopProcessing="true">
     <match url="^(.*)$" ignoreCase="false" />
     <conditions>
      <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
      <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
      <add input="{URL}" pattern="^/favicon.ico$" ignoreCase="false" negate="true" />
     </conditions>
     <action type="Rewrite" url="{ToLower:index.php?p=/{R:1}}" appendQueryString="true" />
    </rule>
   </rules>
  </rewrite>
 </system.webServer>
</configuration>

Answer 1

域名不是RewriteRule中的测试uri的一部分。

您可以使用：

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]

Answer 2

worink解决方案：

DirectoryIndex index.php

RewriteEngine on
 #RedirectToHome
  RewriteRule ^$ /home/ [R=301,L]

 #RedirectToWWW
  RewriteCond %{HTTP_HOST} !^www\. [NC]
  RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]

 #RewriteToParams
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?p=/$1 [QSA]
