@TimeHorse here are the correct rewrites for our platform:
RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-SSL} on
RewriteCond %{HTTP_HOST} ^google\.jeffreycjacobs\.com
RewriteRule ^(.*)$ https://www.google.com/search?q=\%2b"TimeHorse" [R=302,L,NE,QSA]
RewriteCond %{HTTP:X-Forwarded-SSL} on
RewriteCond %{HTTP_HOST} ^timehorse\.jeffreycjacobs\.com
RewriteRule ^(.*)$ https://www.timehorse.com/$1 [R=302,L]
It's done this way because on our platform the SSL happens in Nginx upstream of Apache.
