Using Url rewrites with lls7 is a simple process and it rewrite the urls the same as using htaccess file to do it.
Open Internet Service manager
Click on your site name
In the middle section hit the Url Rewrite
After it is open hit the import rules on the right side.
add the rewrites below in the rewrite rules in the middle section
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ index.php?qa-rewrite=$0&%{QUERY_STRING} [L]
Hit the Apply button on the top right
Go to your admin on your site and choose the top rewrite button
It will not show a green box because windows can not read the htaccess file
but choose the top button anyway and all rewrites will work the same as Apache web server
Hope this helps the windows users
