From this recent thread [webmasterworld.com]:
If you intend to do an external redirect, where the new URL is visible to visitors and search engines, then you should use a canonical URL for the substitution, and set the [R] flag to do a 301-Moved Permanently redirect:
RewriteCond %{QUERY_STRING} ^(this¦that)=([0-9]{3})$
RewriteRule ^5\.shtml$ http://www.example.com/5.shtml?%1=0%2 [R=301,L]
