multiple site with sub domains issues

Ok I got sub domain website to work but having an issue with no subdomain websites showing up at as subdomain websites.

for example:

one domain named example.com it has 2 websites:

www.example.com and sub.example.com

when looking up the site that works completely fine. But if you do a look up on just:

http://example.com it pulls up the http://sub.example.com site.

What is even more odd is there is 2 more site that are setup as:

www.example2.com and www.example3.com which are 2 other domains also.

If you do a lookup with out the www if front of the domain address you get the sub.example.com site.

Each site does have the Auto-Subdomain set to none. And each domain just has the an A record to www and IP.

I have also noticed that when you do not use the www but just the example.com as it does pull up the site and domain that is sub.example.com it seems to be masking the site with it own domain.

Any suggestions?

What the out come should be is that it should shows a 404 page that its not found. Not another website on another domain.

 

Thanks ok that seemed to work. No more redirect to the sub.example.com site.

But one other thing since I have enabled the auto-subdomain, when someone hits the example.com it doesnt redirect to the www.example.com its just a 404 which is ok but if I wanted http://example.com redirect to http://www.example.com where do i set that up and how?

 

Understand,

If an A record of www is set will that confused the auto sub domain of www?

Or do they play hand in hand?

They way it is setup atm is:

dns:
Arecords
www -> ip
sub -> ip

Website is setup as:

example.com with auto-sub domain set to www.


Now when searching for http://example.com you get search engine result looking for the site.

If you type www.example you get the page. My understanding is that if the auto-sub domain is set to www the resquest of example.com should pull up www.example.com correct?

The site doesnt answer to example.com but will answer to a www.example.com

Maybe I am just confused on the records since this is new field I have taken on.

 

Ahh the infamous wildcard. Thank you.

I did do the following and added:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www
RewriteRule (.*) http://www.%{HTTP_HOST}$1 [L,R]

Only on the sites I wanted the www to show.

So far so good.
