Question about .htaccess rules and multisite

Have a question.

I installed Total Cache. When it wrote the rules in the .htaccess file with the multisite rewrite rules in the file, it threw the site into a 500 error. I had to remove the .htaccess file, uninstall and reinstall Total Cache and now it’s working correctly. However, it’s working with only Total Cache rules in the new .htaccess file.

# BEGIN W3TC CDN
<FilesMatch "\.(ttf|ttc|otf|eot|woff|font.css)$">
<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
# END W3TC CDN
# BEGIN W3TC Browser Cache
<IfModule mod_deflate.c>
    <IfModule mod_headers.c>
        Header append Vary User-Agent env=!dont-vary
    </IfModule>
        AddOutputFilterByType DEFLATE text/css text/x-component application/x-javascript application/javascript text/javascript text/x-js text/html text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon application/json
    <IfModule mod_mime.c>
        # DEFLATE by extension
        AddOutputFilter DEFLATE js css htm html xml
    </IfModule>
</IfModule>
# END W3TC Browser Cache
# BEGIN W3TC Minify cache
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^[_0-9a-zA-Z-]+/wp-content/cache/minify/[0-9]+/w3tc_rewrite_test$ /wp-content/plugins/w3-total-cache/pub/minify.php?w3tc_rewrite_test=1 [L]
</IfModule>
# END W3TC Minify cache

What about the former multisite rules under the domain mapping, network setup panel?

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Where do these go?

Seems there was a conflict when .htaccess was being overwritten, which is why the 500 error. Now that I figured that out, do I put the multisite rules back in the htaccess file?
