301 Redirect and query strings

Question

I am looking to create a 301 redirect based purely on a query string see b

OLD URL: olddomain.com/?pc=/product/9999
New URL: newurl.php?var=yup

My normal way of doing this would be

redirect 301 pc=/product/9999 newurl.php?var=yup

But this time I am trying to match a URL that that only contains the domain and a query string...

What is the best way of doing this?

Thanks

Answer 1

I used the following to solve my problems:

RewriteCond %{QUERY_STRING} ^pc=/product/9999
RewriteRule (.*) http://www.newdomain.com/index.php?var=yup [L,R=301]
