You can configure AWS CloudFront for use as the reverse proxy with custom domain names for your Auth0 tenant.

1. Log in to AWS, and navigate to CloudFront.

2. Click Create Distribution.

3. You can choose the delivery method for your content. Click Get Started under the Web section.

4. Configure your distribution settings. Here are the values you'll need to change.

   Setting	Value
   Origin Domain Name	Set this to the Origin Domain Name value obtained from the Auth0 Dashboard during the Custom Domains setup process
   Origin ID	A description for the origin. This value lets you distinguish between multiple origins in the same distribution and therefore must be unique.
   Origin Protocol Policy	Set to HTTPS Only
   Alternate Domain Names (CNAMEs)	Set to your custom domain name (the same one your configured in the Auth0 Dashboard)
   SSL Certificate	Set to the SSL Certificate for your custom domain stored in AWS Certificate Manager (ACM) in the US East(N. Virginia) Region or in IAM.

5. Provide information on the Origin Custom Headers (the Header Name and Value fields appear only after you've provided an Origin Domain Name)

   Setting	Value
   Header Name	Set to cname-api-key
   Value	Set to the CNAME API Key value that you were given immediately after you verified ownership of your domain name with Auth0

6. Configure the Default Cache Behavior Settings. Here are the values you'll need to change

   Setting	Value
   Viewer Protocol Policy	Select Redirect HTTP to HTTPS
   Allowed HTTP Methods	Select GET, HEAD, OPTIONS, PUT, POST, PATCH, DELETE
   Cache and origin request settings	Select Use legacy cache settings.
   Cache Based on Selected Request Headers	Select Whitelist
   Whitelist Headers	Enter User-Agent and click Add Custom >> to add the custom header. Do the same for Authorization, Origin, Referer, Accept-Language, and Accept headers.
   Forward Cookies	Select All
   Query String Forwarding and Caching	Select Forward all, cache based on all

7. Scroll to the bottom of the page and click Create Distribution. You'll see your newly-created distribution in your CloudFront Distributions list. Note that the Status will reflect In progress until the distribution is Deployed.

8. Add a new CNAME record to your DNS for your custom domain pointing to the CloudFront Domain Name for your Distribution. This can be found by clicking on your Distribution ID, under the General tab, Domain Name (for example, e2zwy42nt1feu7.cloudfront.net).
