.htaccess mysite/index.htm to mysite.com

I need to direct requests for mysite/index.htm to mysite.com

Here is my current .htaccess
AddType application/x-httpd-php .php .htm .html 
ErrorDocument 404 mysite.com/sitemap.htm
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mysite.com
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]

Code (markup):

 

Any input would be greatly appreciated.

 

This might be too logical and simple to work

Maybe?

 

I tried that one and the site stops working

 

.................

Who knows

 

That only deals with your document root - what about mysite.com/dirname/index.htm?

Also, what about mysite.com vs. www .mysite.com?

I posted a more complete solution not too long ago -

RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301]
