How to exclude pages from a redirect?

Question

htaccess

Good afternoon! you need to set up a redirect for all pages of the old site (site-old.ru) to a new page of the new site (site.ru/page1/). There were no problems with everything set up

RewriteEngine on
RewriteCond %{HTTP_HOST} ^site-old.ru$ [OR]
RewriteCond %{HTTP_HOST} ^www.site-old.ru$
RewriteRule ^(.*)$ http://site.ru/page1/ [L,R=301]

But now we need to add an exception for some pages of the old site. So that redirects do not work for certain pages of the old site.
There is a question + answer on the toaster How to add an exception to a redirect rule in htaccess?
I do the same.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^site-old.ru$ [OR]
RewriteCond %{HTTP_HOST} ^www.site-old.ru$
RewriteCond %{REQUEST_URI} ^!kontaktyi/$
RewriteRule ^(.*)$ http://site.ru/page1/ [L,R=301]

But then the redirect stops working altogether. Can you tell me what is wrong?

Answer 1

Kind.
Try this
You will probably also need file exclusions

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Pulled from a working project, maybe it will help

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/$
RewriteCond %{REQUEST_URI} !^/index.php$
RewriteCond %{REQUEST_URI} !^/en$
RewriteCond %{REQUEST_URI} !^/en/$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ http://site.com/$1 [L,R=301]
