How to .htaccess redirect this URL with a query string?

Question

While using a WordPress maintenance plugin, I ended up with this query string URL that I now need to redirect to root when the site goes live.

http://mydomain.com/maintenance/?req=http%3A%2F%mydomain.com%2F

What will redirect that URL to simply http://mydomain.com?

I've tried both of these:

Redirect 301 "http://mydomain.com/maintenance/?req=http://mydomain.com/" http://mydomain.com

Redirect 301 "http://mydomain.com/maintenance/?req=http%3A%2F%mydomain.com%2f" http://mydomain.com

Put these lines in your .htaccess file:

Options +FollowSymlinks -MultiViews
RewriteEngine on

RewriteCond %{QUERY_STRING} req=http%3A%2F%2F(.+)%2F [OR] 
RewriteCond %{QUERY_STRING} req=http://([^&]+)(&|$) [NC]
RewriteRule ^maintenance/?$ http://%1? [L,R,NC,NE]

Thanks, works great! How would I do a redirect from the original string to a page like mydomain.com/update/ (that shows a link to mydomain.com) so I can advise users to update bookmarks after they click and go to mydomain.com?

You mean redirecting URI /maintenance/?req=http%3A%2F%2Fmydomain.com%2F to http://mydomain.com/update ? That can be simple done by having last line of above rule like RewriteRule ^maintenance/?$ http://%1/update/? [L,R,NC,NE]

Redirect does only work with the URL path. You need to use the real mod_rewrite to look at the query:

RewriteEngine on
RewriteCond %{QUERY_STRING} =req=http://example.com/
RewriteRule ^maintenance/$ /? [L,R=301]

Thanks, but couldn't get this to work; it was in the correct place, after RewriteEngine on and before the WP rewrite block.
