RewriteRule ^newfolder/(.*)$ /index.html [L,NC]

I em intresting in first line

Answer 1

You can use negation in RewriteCond:

RewriteCond %{HTTP_USER_AGENT} !(opera|navigator|safari) 
RewriteRule ^newfolder/(.*)$ /index.html [L,NC]

PS; Take note of RewriteCond %{HTTP_USER_AGENT} !navigator which means all user agents except navigator.
