Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : newbie subdomain question

[deko]

If I have 4 different domains, can I pile them up like this:

primary.com
sub-a.primary.com
sub-b.primary.com
sub-c.primary.com

I assume that's not a problem, but how do I route the traffic?

DNS will point sub-a.com (and b and c) to primary.com, but how do I get requests for

www.sub-a.com

to

www.sub-a.com.primary.com

Do I use an .htaccess rewrite?

Something like:

RewriteCond %{HTTP_HOST} ^www.sub-a.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^sub-a.com$ [NC]
RewriteRule ^(.*)$ http :// www .sub-a .primary.com/

Is there any other way to do it?

Thanks in advance.

I haven't checked your rewrite syntax, but the idea seems to be OK. Alternatively you could setup the subdomains in your server configuration if this is a dedicated server.

I think an htaccess rewrite should work - just looking for a sanity check.

It's not a dedicated server. The host allows up to 10 subdomains. I don't know of any other way to make use of them unless I use htaccess rewrites.

Are you using cpanel? Or anything similar? Cpanel has a concept of "parked domains" which does all of this for you. It also has a concept of "addon" domains which essentially have their own private webspace kept in a subdirectory of your main site.

as brianoz said, cPanel is very useful with that cases, if you are on shared, then use the htaccess

Also, if you park the domains, you can use either an http redirect (can be hard to get right) or a test in your index.php for the main site.
