A particular page opens in the url?

Hi all...

I have setup a html page and uploaded it with many other pages under a domain.

How can I setup it such that that particular page opens when my url is opened.

Currently I get this when someone visits the url:

I want that when someone visits the url, homepage.htm opens automatically

 

make a .htaccess file and write this then place it on ftp
DirectoryIndex index.html homepage.htm

 

thanks this worked

 

The other option would just have been to rename the homepage file index.html instead.
