HTACCESS 403 : How to block url with a specific character?

I'm using WordPress and I have some duplicate URL by spammer

https://www.example.com/caterory/article-name/ ==> OK

https://www.example.com/caterory/article-name/?vn/2022-06-24fivhg585.html ==> Wrong

I would like to block this kind of URL with string ?vn/

I tried this but it's not working

RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} (googlebot|bingbot) [NC]

RewriteCond %{QUERY_STRING} ^*vn/ [OR]

RewriteCond %{REQUEST_URI} ^*vn/

RewriteRule ^ - [F]

Any ideas?

Solution

  • The following should work for you. Make sure to place it at the top or before your WP rewriterule block .

    RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} (googlebot|bingbot) [NC]

RewriteCond %{QUERY_STRING} ^vn/ [NC]
RewriteRule ^ - [F]

    If you want to test this rule yourself , just comment out or remove the condition line RewriteCond %{HTTP_USER_AGENT} (googlebot|bingbot) [NC] and visit any URL starting with the querystring ?vn . You will get a 403 forbidden error.
