How to add exception to RewriteRule?

Question

htaccess

Hello!
Please help me set up a redirect: redirect all requests to http://www, except for two requests: https://domain.ru/pay/check and https://domain.ru/pay/aviso they should work with/without www

RewriteCond %{HTTP_HOST} ^domain.ru$ [NC]
RewriteCond %{REQUEST_URI} !^pay/check //не помагает
RewriteRule ^(.*)$ http://www.domain.ru/$1 [R=301,L]

(the problem appeared after the main mirror was changed by Yandex, and the cash desk. Yandex cannot change the address for sending requests in any way)

Answer 1

this condition helped.
RewriteCond %{HTTP_USER_AGENT} !yandex.money [NC]
