Redirect homepage to specific subdirectory

Question

I have a wordpress site and I need to redirect the homepage " http://members.slateadvisers.com/ "

to the registration page

" http://members.slateadvisers.com/?action=registeruser&subscription=1 "

How can I do this with htaccess?

Answer 1

Insert this rule on top of all the rules just below RewriteBase line:

RewriteCond %{HTTP_HOST} ^members\.slateadvisers\.com$ [NC]
RewriteRule ^$ ?action=registeruser&subscription=1 [L,R=301]
