@Kamre Goutham

Thank you for reaching out.

Just a quick question here to understand the need of redirecting the root domain to a www domain, have you considered onboarding a root or apex domain to Azure Front Door instead?

As documented here The DNS protocol prevents the assignment of CNAME records at the zone apex. For example, if your domain is contoso.com; you can create CNAME records for somelabel.contoso.com; but you can't create CNAME for contoso.com itself. This problem can be resolved by using alias records in Azure DNS. Unlike CNAME records, alias records are created at the zone apex. Application owners can use it to point their zone apex record to a Front Door profile that has public endpoints. Application owners point to the same Front Door profile that's used for any other domain within their DNS zone. For example, contoso.com and www.contoso.com can point to the same Front Door profile.

Please let me know if you have any questions. Thank you!

HI Chaitanya,

I added www.csonline.com in the Azure Frontdoor custom DNS section and added Azure-generated DNS TXT record and CNAME record to public DNS.

When i browse www.csonline.com the page loads but without the www (https://csonline.com) the page doesn't work.

@Kamre Goutham

Thank you for getting back.

Based on your statement above

I added www.csonline.com in the Azure Frontdoor custom DNS section and added Azure-generated DNS TXT record and CNAME record to public DNS.

From your question above, I understand that you are using classic Front Door SKU. For classic FrontDoor the custom domain is verified using CNAME record as documented here https://learn.microsoft.com/en-us/azure/frontdoor/front-door-custom-domain#map-the-permanent-custom-domain

For Standard & Premium SKU the custom domain is verified using DNS TXT record as documented here:

https://learn.microsoft.com/en-us/azure/frontdoor/domain#domain-validation

Can you please confirm which AFD SKU you are using?

Can you please let us know what type of CNAME record you have added to your domain in your Domain registrar's website?

For example, if your domain is registered as csonline.com on your domain registrar. Then you will add a CNAME record with the host value of "www" pointing towards <hostname>.azurefd.net. This experience may vary as per the domain registrar used. You can refer to this documentation for additional details.

Please let me know if you have any additional questions. Thank you!
