Server Name Indication (SNI) with Windows Authentication with site using CDN

Category: azure cdn


bamireddi on Wed, 28 Mar 2018 07:06:49

We have the following setup in IIS 8.0 and the site is Windows Authenticated.

One site setup in IIS and uses both port 80 and port 443 for setting up multiple domains. Each domain setup with port 443 has SNI enabled.

Now with this setup, when we purge the website using Azure CDN, the Azure CDN website returns 502 Bad Gateway. 

Does anyone encounter this issue and have a resolution in place, please let me know.

Thanks in advance!

Can you show us the error you get? 

Do you mean that the purge operation itself fails? Or that the endpoint returns the error after the purge?

Are you using Verizon standard/premiuim, or Akamai CDN profile?

How long are you waiting after purge to try accessing?

How long does the 502 issue last?
