Redirect All Parameters to Another domain

[clickfire]

I'm attempting to redirect all URLs with parameters to the main page of another domain.

Existing URL Example:
[olddomain.tld...]

Needs to Redirect to:
[newdomain.tld...]

This is the code I'm using but it isn't working. The domain changes in the browser but the parameters remain.

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /support/demo\.php\?id=([^&]+)&series=([^&]+)\ HTTP/
RewriteRule ^(.*)$ http://www.newdomain.tld/ [R=301,L]

Add a question mark after the target URL to clear the parameters.

Your code does not redirect "all" parameters.

It only redirects for /support/demo\.php\?id=<anything>&series=<anything>

Ah, the question mark after the target URL made it work. Thanks!

Be careful to clearly comment your code so you know exactly what it does when you have to look at it again several months or years in the future.
