• Simple 301 redirect; how do I get it to drop the query string?

  - by Throlkim

  Hopefully there's a simple solution to this. I'm setting up a redirect for old search listings, but I don't want any of the query string to carry over. The current rule is: redirect 301 /blog http://newdomain.com But this would redirect the following: http://www.olddomain.com/blog/2009/11/article-name-etc To this: http://newdomain.com/2009/11/article-name-etc When I just want: http://newdomain.com Can this be done in the simple 301 redirect, or will I have to write a mod_rewrite rule?
