We have been running SP successfully for past few months. We have been trying to show customized pages to repeat visitors based on the domain userid in the cookie, and our knowledge about the past interests of the visitor.
I now wish to identify an anonymous visitor by reading the network user id instead of the domain userid - is that not available in the cookie? How do I do that?
@cbragg: one thing to stress is that because the collector uses an AWS Elastic Load Balancer, you can only attach a single SSL certificate to it. (This is an limitation with Amazon’s Elastic Load Balancers.) That means that if you did run multiple CNAMEs to a single collector, only one of those CNAMES would work on HTTPS.
I think I have misunderstood the cookie setting component - the collector simply collects information transmitted back from the web application (it does not set cookies).
The key here is setting the cookie as @alex stated above, to allow subdomains to collect the domain_userid and other snowplow cookie set variables.
