I know with a simple redirect one (Sub-)Domain or Folder to another i can get rid of a string like this
RewriteEngine On
RewriteRule (.*) http://www.domain.tld/? [R=301,L]
I know how to get rid of it when it is a simple file too.
But when it comes to the Rootdomain itself (http://domain.tld/?Stringwhatsoever), i am at a loss here. My last try used a modified version of a redirect I used to redirect files and folders around and that worked pretty nicely and also removed the query, but it ended up in a redirection error.
RewriteRule ^ http://domain.tld/? [L,NC,R=301]
So i have no clue how to get rid of Query Strings at urls without breaking it.
