Load default view with CI

[eluser]Unknown[/eluser]
Hello! Need help with this:
Had my site with this URL mysite.com/index.php/controller/view1
Removed controller name from URL with routes.php
with .haccess removed index.php and site works with mysite.com/view1.

But it doesnot work with simple mysite.com
How to make that with mysite.com called mysite.com/view1 ?

Code:

DirectoryIndex view1.php

not work.

And trying this one

Code:

RewriteCond %{HTTP_HOST} ^mysite.com$ [NC]
RewriteRule ^(.*)$ http://mysite.com/view1/$1 [R=301,L]

Thanks
