Apache htaccess remove trailing slash on internal redirect with parameter

Question

I have a subdirectory called /al on my website, which I wish to redirect to the main page, with a language setting.

So I have the following rule:

Redirect permanent /al /?lang=en

But after verification with cURL, I am getting sent to /?lang=en/ instead. How can I remove the trailing slash?

Answer 1

将RedirectMatch用于正则表达式功能：

RedirectMatch 301 ^/al/?$ /?lang=en
