What is wrong in this rule?
RewriteRule ^page\?v=([^/]+)$ page.php?v=$1 [L,NC]
I just want to make the URL looks like that
http://www.domainname.com/page?sk=info
Also, you can find additional information about this mod_rewrite case here: http://wiki.apache.org/httpd/RewriteFlags/QSA
And another SO entry about this issue here.
