Here is your first post in the thread:
-------------------------------------------------------------
but this isn't 100% truth
I ve modified my .vhost from apache2
Restarted apache2 and works fine
But, if I reboot, ispc restore the .vhost file
Why?

So were did you ask this question there? The first time you asked
the question how to rewrite domain.com to
www.domain.com in your last post #26.
There is no redirect needed as you get the same content of the website when you
enable the auto subdomain when you enter
www.domain.com
or just domain.com. Thats what the function is intended to do and
this is what the function does.
If you automatically want to rewrite domain.com to
www.domain.com
which is not nescessary but can be done of course e.g for search engine optimisation, you can do this with apache rewrite rules that can be added to the apache directives field (See my post #8 part 3) in case that you want to have other rewrite rules then the ones that ispconfig adds on the rewrite tab.
For example just add:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^domain.com [NC]
RewriteRule ^/(.*)$ http://www.domain.com/$1 [R]
