redirect old .asp files to new .html files using htaccess

I have moved my old .asp site from windows server to .html files on a linux server using nginx I dont have access to the conf file so i need to redirect the old .asp pages to the new .html.

The .asp files exist on the new server but in htaccess i have this entry :

AddType application/x-httpd-php .asp Redirect index.asp http://dvmark.com/index.html

it doesn't work. When youtype in dvmark.com/index.asp all you get is the html text display of the index.asp page. I have tried several different ways to redirect and no luck. If I delete the .asp pages I get sent to my 404 page which is OK but I would really want the redirect to work so the user doesn't have to find the page they are looking for in the sitemap.
