How to write a redirect to nginx - cut a substring?

Question

Nginx

Links like
/catalog/f-clear/
/catalog/obuv/f-clear/name/
/catalog/obuv/f-clear/
We need to write a rule so that /f-clear is always removed from the link

Answer 1

Return a permanent redirect (301) to a link without /f-clear
https://nginx.ru/ru/docs/http/ngx_http_rewrite_mod... And as a [bad] option, you can remove this /f-clear https when serving content ://nginx.ru/ru/docs/http/ngx_http_sub_module....

sub_filter_once off;
sub_filter_types text/html;
sub_filter "/f-clear" "/";
