How to verify if instance is configured with ADCv2 ?

[Sunny45]

Hello Team,

We want to setup MID server for mutual authentication and for that following are pre-requisites. 

How can we verify that instance has to be configured with ADCv2 ?

Please advise.

Thanks.

If you have a support account, check out this KB. Towards the bottom of the article, in step 10, you're instructed to run a curl command against your instance. If you get a specific value back, ADCv2 is installed

10. How do I know if our instance has been migrated already?
    Check the “server” header on a request sent to the instance:

% curl -I https://<instance>.service-now.com

HTTP/2 200

server: snow_adc

date: Thu, 08 Oct 2020 19:23:25 GMT

content-length: 0

set-cookie: BIGipServerpool_<instance>=ccf42229b33f11e524d130641f6f35ae; httponly; secure; path=/

set-cookie: JSESSIONID=FA3C59E9BD01585A601F26E417ED0FA6; Path=/; HttpOnly; secure

strict-transport-security: max-age=63072000; includeSubDomains

    If the server header has a value of “snow_adc”, the instance is being served by ADCv2

Hope this helps

Thanks Matthew, yeah I saw that document, but I am not familiar with curl. Is it possible to get equivalent in Java script? 

Please advise.

Thanks.

Looks like you can also view it from within the dev tools in your browser.

In your browser (verified on Chrome and Firefox), open up your developer tools and click on the Network tab, then log into your instance.

In that Network tab, click on any of the entries that you see populating on the left. You'll then see some details populate on the right. Click on the Header tab in the panel on the right and you should see that "Server" header called out in the article. Per that article, if you have snow_adc as the value, you're on ADCv2

Awesome Matthew. That's exactly I was looking for.

Thanks.
