RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule . /index.html [L]

Answer 1

This should work for you:

RewriteEngine On

RewriteCond %{REQUEST_URI} !^/(?:index.html|1/[1-3]/.*)$ [NC]
RewriteRule ^ http://ssvwv.com/ [L,R=302]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.html [L]

Issue is that last rule is rewriting to /index.html and when mod_rewrite loops again URI becomes /index.html and RewriteCond %{REQUEST_URI} !^/1/(?:1|2|3)/.*$ returns true thus redirecting to http://ssvwv.com/. That's why you need to skip /index.html from first rule as well.
