The following should work:
Code:
RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^/$ http://www.domain.com/index.html [R=301,L]
This rule is only activated when "/" (the site root) is requested, and redirects the user to "/index.html". This needs to be fairly specific, because otherwise, the rule could be triggered when subfolders are requested. If you want this rule triggered for all subfolders as well, use the following:
Code:
RewriteCond %{REQUEST_URI} ^.*/$
RewriteRule ^(.*)/$ http://www.domain.com$1/index.html [R=301,L]
