问题
I currently have an Heroku app that is being served over a CDN. I have just added Fastly to my Heroku app as an addon and I am struggling to configure it properly. Here is my current configuration:
I have my domain registered on GoDaddy with the following CNAME configuration:
Host: www
Points to: my-site-herokuapp-com.global.ssl.fastly.net
TTL: Custom
Seconds: 600
Here is the GoDaddy forwarding configuration (not sure if this matters):
Forward to https://www.my-site.io/
(301 & forward only)
Here is my fastly configuration:
Domains:
my-site-herokuapp-com.global.ssl.fastly.net
*Provisioned for my-site via Heroku*
my-site.herokuapp.com
*Provisioned for my-site via Heroku*
www.my-site.io
And finally in Heroku in the domains configuration section of my app here are my settings:
Domain Name: my-site.io
DNS target: darwinian-kumquat-123456.herokudns.com
Domain Name: www.my-site.io
DNS target: serene-trout-123456.herokudns.com
Before I tried to make this change I had the CNAME pointing directly to: serene-trout-123456.herokudns.com an it was working fine. However after updating this value to the new Fastly value: my-site-herokuapp-com.global.ssl.fastly.net Fastly directs the site to my-site.herokuapp.com instead of just https://www.my-site.io. I followed the instructions listed here so not entirely sure where I have gone wrong. Any ideas?

Probably because you used redirect 301 and you are using the same browser as before before cleaning cache and data.
301 redirects are recomended only for very limited cases: once done the browsers will NOT refresh again any data from the original server.
There are plenty of posts regarding redirection 301, for example:
