使用htaccess删除结尾的斜杠，但保留查询字符串

Question

I am using following directives in my htaccess to remove trailing slashs from my uris to prevent duplicate content. However these directives also remove any query string, that might be present.

RewriteCond %{HTTP_HOST} ^(www.)?mydomain\com$ [NC]
RewriteRule ^(.+)/$ http://www.mydomain.com/$1 [R=301,L]

I'd like to know how to remove a potential trailing slash from my URI, but also preserve query strings.

Answer 1

There's a RewriteRule option flag for that: QSA .

Appends any query string from the original request URL to any query string created in the rewrite target
