How to remove the slash at the end of the URL in this htacess?
For links to be of the form site.ru/page1 , not site.ru/page1/
RewriteEngine On

# The directive includes redirects !!!!
RewriteBase /
# Without the directive "(.*) = /$1" will be /var/wwww/site/web/$1 with the directive = /$1
Options +FollowSymLinks
# Allows following symbolic links.

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

#RewriteCond %{HTTPS} !on
#RewriteRule ( .*) https://%{HTTP_HOST}%{REQUEST_URI } [R=301,L]

RewriteCond %{THE_REQUEST} //
# Check if slash (//) is repeated more than twice.
RewriteCond %{QUERY_STRING} !http(s|)://
# Make sure it's not a url in GET
RewriteRule .* /$0 [R=301,L]
# Eliminate all unnecessary slashes.
RewriteCond %{REQUEST_URI} \..+$
# If the file contains a dot.
RewriteCond %{REQUEST_FILENAME} !-d
# And it's not a directory.
RewriteCond %{REQUEST_FILENAME} -f
# Is a file.
RewriteCond %{REQUEST_URI} ^(.+)/$
# And there is a slash at the end of the URL.
RewriteRule ^(.+)/$ /$1 [R=301,L]
# Remove slashes.

I think here you can easily figure out what is responsible for what.
pay attention that there are two rules at once and adds and deletes
Depending on whether it is a directory or a file.
so if you need to remove then remove two rules at once.
