This is the solution from my Apache Cookbook to redirect everything to SSL. I assume in the main server portion (doesn't really say) have the following directives.
RewriteCond "%{SERVER_PORT}" "^80$"
RewriteRules "^(.*)$" "https://%{SERVER_NAME}$1" [R,L]
Or just in the main server section you can also use the directive
Redirect /
https://name_of_server
to accomplish the same thing as the above.
