为什么我的子域名重定向到我的主要领域？ [英] Why is my subdomain redirecting to my main domain?

问题描述

因此​​，基本上，我有一个子域， m.mydomain.com.au 虽然我每次访问它，我重定向到 WWW。 mydomain.com.au/m 。

例如，如果我试图去 m.mydomain.com.au/contact.php ，我是自动重定向到 WWW。 mydomain.com.au/m/contact.php

我从来没有尝试之前修改我的的.htaccess 文件，但我相信这是目前造成问题的原因。

所有帮助和建议，大大AP preciated。

下面是我的全的.htaccess 文件：

 选项+了FollowSymLinks

＃使用mod_deflate模块，以COM preSS静态文件

RewriteEngine叙述上


的RewriteCond％{QUERY_STRING} base64_en code [^（] * \（[^）] * \）[OR]
的RewriteCond％{QUERY_STRING}（小于|％3C）（[^ s]的* S）+ CRIPT *。（大于|％3E）[NC，OR]

#RewriteBase /


。重写规则*  -  [E = HTTP_AUTHORIZATION：％{HTTP：授权}]

的RewriteCond％{REQUEST_URI}！^ /指数\ .PHP

的RewriteCond％{REQUEST_URI} /component/|(/[^.]*|\.(php|html?|feed|pdf|vcf|raw))$ [NC]

的RewriteCond％{} REQUEST_FILENAME！-f

的RewriteCond％{} REQUEST_FILENAME！-d

重写规则。*的index.php [L]
 

解决方案

假设这两个子域和主域名具有相同的文档根目录（因此使用相同htaccess文件），这是造成重定向规则：

 的RewriteCond％{HTTP_HOST}！^ WWW \ .mydomain \ .COM \ .AU
重写规则^（。*）$ http://www.mydomain.com.au/$1 [R =永久，L]
 

这基本上是说，如果访问的不可以 www.mydomain.com.au ，重定向到 HTTP ：//www.mydomain.com.au/

您需要添加额外的检查，以便它不重定向你的子域名：

 的RewriteCond％{HTTP_HOST}！^ WWW \ .mydomain \ .COM \ .AU $ [NC]
的RewriteCond％{HTTP_HOST}！^ M \ .mydomain \ .COM \ .AU $ [NC]
重写规则^（。*）$ http://www.mydomain.com.au/$1 [R =永久，L]
 

或者只是重定向没有 WWW的域名：

 的RewriteCond％{HTTP_HOST} ^ MYDOMAIN \ .COM \ .AU $ [NC]
重写规则^（。*）$ http://www.mydomain.com.au/$1 [R =永久，L]
 

So basically, I have a subdomain, m.mydomain.com.au although every time I visit it, I am redirected to www.mydomain.com.au/m.

For example, if I attempt to go to m.mydomain.com.au/contact.php, I am automatically redirected to www.mydomain.com.au/m/contact.php

I have never attempted to modify my .htaccess file before, but I believe it is causing the problem at the moment.

All help and suggestions is greatly appreciated.

Here is my full .htaccess file:

# Use Mod_deflate to compress static files
<ifmodule mod_deflate.c>
<filesmatch ".(js|css|ico|txt|htm|html|php)$">

</filesmatch>

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

RewriteCond %{REQUEST_URI} !^/index\.php

RewriteCond %{REQUEST_URI} /component/|(/[^.]*|\.(php|html?|feed|pdf|vcf|raw))$ [NC]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule .* index.php [L]

解决方案

Assuming that both your subdomain and main domain have the same document root (and thus use the same htaccess file), this is the rule that's causing the redirect:

RewriteCond %{HTTP_HOST} !^www\.mydomain\.com\.au
RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [R=permanent,L]

This essentially says, if the domain is not www.mydomain.com.au, redirect it to http://www.mydomain.com.au/.

You need to add an additional check so that it doesn't redirect your subdomain:

RewriteCond %{HTTP_HOST} !^www\.mydomain\.com\.au$ [NC]
RewriteCond %{HTTP_HOST} !^m\.mydomain\.com\.au$ [NC]
RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [R=permanent,L]

Or only redirect the domain without the www.:

RewriteCond %{HTTP_HOST} ^mydomain\.com\.au$ [NC]
RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [R=permanent,L]
