“www” on subdomains
Many websites offer subdomains, but most of them fail when they are accessed with a “www”, such as www.subdomain.domain.com. The reality is that many users always write the three ‘w’s every time they write a web address. For this reason, I will explain how easy it is to configure your website to work with the “www” before a subdomain.
The trick is in the CNAME configuration. Just as you assigned a CNAME to your subdomain.domain.com, you now assign the “www.subdomain.domain.com” as a CNAME to “subdomain.domain.com”
An example entry of your Custom DNS Setting should look like this:
CNAME Record subdomain IN CNAME somesite.site.com
That will map your http://subdomain.domain.com to the site.com location. When users type in the “www” they will be sent to a “Page not Found” error page. To fix this, you add the other CNAME Record so that now it looks like this:
CNAME Record subdomain IN CNAME somesite.site.com
CNAME Record www.subdomain IN CNAME subdomain.domain.com
This last entry will fix your “www” problem for that subdomain.
Will this work if you have mutiple subdomains?
Thank you!
Yes, this works for multiple subdomains. Just repeat these steps for all subdomains.
