The homepage of my forum is also indexed under www.domain.tld/?action=profile&uid=XY (=duplicate content).
I'd like to redirect it to www.domain.tld/ but can't get it to work. I tried variations of the following to no avail (server error).
RewriteCond %{QUERY_STRING} ^action=profile&uid=XY$
RewriteRule ^(.*)$ http://www.domain.tld/? [L,R=301]
