Hi, I'm trying to use some rule on my project to remove www from the beginning of the URL but I've some problem.

my server structure is:

domain.com/beta_folder
domain.com/beta_folder/page+type
domain.com/beta_folder/page+type/content+name
domain.com/beta_folder/page+type/content+name/edit
domain.com/beta_folder/page+type/content+name/etc.

domain.com/beta_folder/.htaccess //here is where my htaccess is

beta_folder is the site folder, and content+name are content vars, created to retrieve pages from the database.

the site works perfect with this rules

RewriteEngine On
RewriteRule ^(page\+type/)([a-zA-Z0-9_+-]+)[/]?$ page_folder/page.php?varname=$2

My intention was to remove www, so I've added this rule but it isn't effective

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://domain.com$1 [R=301,L]
RewriteRule ^(page\+type/)([a-zA-Z0-9_+-]+)[/]?$ page_folder/page.php?varname=$2

My problem starts if I digit www in front of my domain name:

this works

http://domain.com/beta_folder/page+type/content+name

if i write

http://www.domain.com/beta_folder/page+type/content+name

the rewrite rule redirect me at

http://www.domain.compage+type/content+name

if i remove the www rules, the problem still active

unfortunately, I can't make a public test for my domain

basically, if I write

 http://www.domain.com/beta_folder

the rules sends me to

 http://domain.com/

where I'm wrong?
