这是我的htacess文件：

This is my htacess file:

RewriteEngine on    
RewriteCond %{HTTP_HOST} !^www.
RewriteCond %{HTTP_HOST} ^(.*).mydomain.com(.*)
RewriteRule .* inside.php?tx=%1&filter=%2 

此网址：hello.mydomain.com去www.mydomain.com/inside.php?tx=hello~~V 那是正确的。

This url: hello.mydomain.com goes to www.mydomain.com/inside.php?tx=hello Thats correct.

现在我需要这个网址hello.mydomain.com/bye/去www.mydomain.com/inside.php?tx=hello&filter=bye~~V，但不起作用。只到www.mydomain.com/inside.php?tx=hello~~V

Now i need this url hello.mydomain.com/bye/ goes to www.mydomain.com/inside.php?tx=hello&filter=bye, but don't work. Only goes to www.mydomain.com/inside.php?tx=hello

这htaccess的是忽略了第二个变量（再见）。请帮助。

This htaccess is ignoring the second variable (bye). Help please.

推荐答案

％{HTTP_HOST} 仅包含主机名（ hello.mydomain。 COM ），那么你的第二个反向引用不具有任何东西。改变你的重写规则以下是应该给你期望的行为：

%{HTTP_HOST} only contains the host name (hello.mydomain.com), so your second backreference doesn't have anything in it. Changing your RewriteRule to the following should give the behaviour you're expecting:

RewriteRule ^([^/]*) inside.php?tx=%1&filter=$1 

编辑：要更正您的评论描述的情况，整个规则集应该如下：

To correct the situation described in your comment, the entire ruleset should be as follows:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.
RewriteCond %{HTTP_HOST} ^(.*).mydomain.com(.*)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*) inside.php?tx=%1&filter=$1
