Hello

here is a piece of htaccess i am stuck converting into nginx rewrite conventions :

RewriteCond %{QUERY_STRING} ^sms_ss= [OR]
RewriteCond %{QUERY_STRING} ^scvds=
RewriteRule ^(.*)$ http://www.mysite.com/$1? [R=301,L]


I am trying something like

if ($args ~ "sms_ss= (.*)") {
rewrite ^ /(.*)=$args? break;
}

Not working


Any advice would be appreciated thanks
