Adobe collects data on your site by receiving an image request generated by the visitor. The trackingServer variable determines the location an image request is sent. If this variable is not defined correctly, your implementation can experience data loss.
Tracking server can be 3rd party tracking server or first party tracking server.
Host name is required for the setup of FPC.
Hostname can be uniqueidentifer.domain.com
As an example we can pick following for ourpcgeek.com
- For secure you can pick smetric.ourpcgeek.com
- For non-secure you can pick metric.ourpcgeek.com
- For secure you can pick smetric.me.ourpcgeek.com
- For non-secure you can pick metric.me.ourpcgeek.com
A tracking server is considered as First party when the tracking server contains the domains in it and you have to use that tracking server against that domain only.
For example: smetric.me.ourpcgeek.com will be treated as first party only for domain me.ourpcgeek.com and its subdomains.
If you try to use it with any other domain(like here domain is ourpcgeek-stage2.adobetest.com), it will be treated as Friendly third party tracking server.
Also me.ourpcgeek.com is the subdomain of ourpcgeek.com hence we do not need to set up tracking server separately for me.ourpcgeek.com.
We can use smetric.ourpcgeek.com for both ourpcgeek.com and me.ourpcgeek.com. It will be treated as First party for both of them.
