Is it possible to have 'www' resolve to subdomain?

[amanda2]

Not a networking person by any stretch of the imagination, so I’m not sure I’m asking this question correctly:

Is it possible to have ‘www.b2b.drinkrebellious.com’ resolve to ‘b2b.drinkrebellious.com’? We think new customers might include the ‘www’ out of habit.

If it’s possible, can you let me know where I can find specific directions?

Thanks!

You could create a redirect, but the first issue is that Cloudflare’s edge certificate doesn’t go that deep:

Subdomain too deep

This tutorial covers a possible reason for the SSL_ERROR_NO_CYPHER_OVERLAP and ERR_SSL_VERSION_OR_CIPHER_MISMATCH errors (Firefox and Chrome respectively) when seen on a subdomain. The Cloudflare universal certificates cover example.com and *.example.com. This means that it covers any subdomain one level below the domain you signed up with. It will cover www.example.com and subdomain.example.com, as these are one level below the root domain, example.com. The certificate will not cover www.sub…

If you wish to proceed, you can then do something like this:

Redirect www.example.com to example.com

This tutorial covers redirecting www.example.com to example.com when using Cloudflare, to do the opposite, please see Redirect example.com to www.example.com. You should replace all instances of example.com in the screenshots with your domain. Step 1, The DNS Record: The first thing you will need is a DNS record for www, set to . This can point to any IP address as the redirection page rule will execute first. I would recommend pointing it to 192.0.2.1, a dummy IP. [image] Step 2, …

@sdayman Thanks for your quick response.

Some additional info: The domain drinkrebellious.com is for our B2C store on Shopify. The b2b subdomain is a WP site hosted on WPengine. The A record is for drinkrebellious.com. There are CNAME records for ‘b2b’, which point to WPengine, and ‘www’, which points to Shopify.

The b2b CNAME is proxied and the Proxy Status for www is ‘DNS Only’.

My hunch is that because we have things split this way, we can’t have www.b2b.drinkrebellious.com resolve (but I may not know what I’m talking about).

It doesn’t much matter where everything is, except that your DNS is here. So you’ll need a DNS record called just www.b2b (because the domain is added on automatically). If it’s set to , then you’ll need that ACM certificate. If it’s set to , then your server will need to do the redirect instead of the Page Rule in the tutorial.

All in all, I don’t think it’s worth the effort to accommodate a ‘www’ prefix in front of a subdomain. People will either type in what they see, or they’ll follow an existing link.
