There are many posts on this issue, but I couldn't find the answer. When I tried to change htaccess it caused problems.
www.xyz.com points to www.xyz.com/mysite This works great and user only sees www.xyz.com Unfortunately if someone types www.xyz.com/mysite they also get the same site, but they see www.xyz.com/mysite
Ideally when they type www.xyz.com/mysite it will show www.xyz.com.
Thank You for your help
