is this an Apache thing?

I have a website that when I access certain directories, it removes the "www" from the address. What causes this? It's on a shared host with other sites and this is the only one that does this.

for example, my main page is located at hxxp://www.mysite.com but when I type hxxp://www.mysite.com/subdirectory it forwards to hxxp://mysite.com/subdirectory hence removing the www.

Sound like a .htaccess thing.

It's probably your .htaccess file, change to this and non www will always go to www.

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^yoursite.com [NC]
RewriteRule ^(.*)$ http://www.yoursite.com/$1 [L,R=301]

Thank you, that did remedy the issue, makes me wonder why I didn't have this problem when it was on another host & i don't have this happening with other sites on my current host.
