I have problem with google ads it's add query string on the URL with query string and due to that the website return 404 error.
Example :
when you click the below link
https://boutique.celinedion.com/en?test=test
it will redirect to with 404 error.
https://boutique.celinedion.com/en/en?test=test
but in other sites it's work fine example:
https://collection.volvocars.com/en?test=Test
redirect to (but remove the query string but i want to keep it!)
https://collection.volvocars.com/en/
I try to use IIS rewrite rule but it doesn't work
any ideas to fix this problem
Thanks in advance
