301 redirect without passing variables

[Samjam]

With all kinds of 301 redirects i found, all parameters at the end of the url are passed to the new domain, which creates lots of duplicate content, as the parameters are no longer needed:
for example:

Redirect 301 / http://www.example.com/

causes: http://www.example.com?var=1
to redirect to: http://www.example.com/?var=1

but i want it to redirect to http://www.example.com/

The only thing i found in hours of searching is this:

Redirect 301 / http://www.example.com/?

which removes all parameters, but leaves the ? at the end, which isn't really clean either, and i suppose counts as duplicate content too.

Any help is greatly appreciated! =)

Use mod_rewrite rather than mod_alias. By appending a "?" to the substitution URL, the query string is removed, but the "?" itself will not appear in the redirected-to URL.

Wow, that really worked! Thank you so much jdMorgan! =)

Thats the code i now use, for anyone interrested:

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.example.com/? [R=301,L]
