.htaccess 使用htaccess加载特定域的页面

我有一个domain example.com和main example.com-我希望example.com指向main example.com/social/pre/register/121，它已经由htaccess文件驱动

我不知道该怎么办。。我已将这两个域指向同一目录。我在一个虚拟共享服务器上，所以我使用directadmin和php/codeigniter

该站点使用下面列出的codeigniter的标准htaccess文件

RewriteEngine On
RewriteBase /upd8r_jul

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

您需要在

%{REQUEST_URI}

行中添加斜杠，因为它们看起来都像

/something

，而不是

something

，就像URI在

重写规则

中用于匹配。但这确实会影响你所问的问题

如果要重定向

http://example.com/

至

http://mainexample.com/social/pre/register/121

然后将这些规则添加到htaccess文件中已有的规则之上：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC]
RewriteRule ^$ http://mainexample.com/social/pre/register/121 [L,R=301]
