How to set up an exception for a redirect from a domain to a subdomain?

Question

htaccess

I use a redirect on the site from a domain to a subdomain:

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} robots.txt$ [NC]
RewriteRule ^([^/]+) $1 [L]
RewriteRule (.*) https://1.domain.com/$1 [R=302,L]

But it is necessary to make an exception for the sitemap.xml file, in general it is important that it opens at domain.com/sitemap.xml, how to do this?

Answer 1

RewriteEngine On

RewriteCond %{REQUEST_URI} !^/robots\.txt$
RewriteCond %{REQUEST_URI} !^/sitemap\.xml$
RewriteRule (.*) https://1.domain.com/$1 [R=302,L]

Or

RewriteEngine On

RewriteRule ^(robots\.txt|sitemap\.xml)$ - [L]

RewriteRule (.*) https://1.domain.com/$1 [R=302,L]
