I'm working on a ecommerce site which uses both Data Insertion Api and javascript (AppMeasurment.js) to send data to Adobe collecting servers. I need to read the s_vi cookie value in order to send data from backend.
When I look a the requests in firefox, the s_vi cookie has a different domain than my domain (I'm testing on localhost), so I can't read it.
Any help is appreciated.
The s_vi cookie is set in a response from your Data Collection Server (e.g. 'metrics.yoursite.com'), so you can only see that cookie in a matching domain space (e.g. 'yoursite.com'.)
To test on localhost, you could try using Fiddler to map requests for 'yoursite.com' to your localhost (or machine name) so your browser will send the cookie with those requests.
