Install Ionic's Isapi Rewrite Filter http://iirf.codeplex.com/ and use this rewrite code:
RewriteRule ^(.*)billingapi\.aspx(.*) - [L,NC]
RewriteRule ^(.*)filemanager_upload_frame\.aspx(.*) - [L,NC]
 RewriteRule ^(.*)filemanager_upload\.aspx(.*) - [L,NC]
 RewriteCond %{HTTPS} off
 RewriteCond %{SERVER_PORT} ^80$
 RedirectRule ^/(.*)$ https://%{SERVER_NAME}/$1 [R=301]
