Investigate sitekey in MV3

Background

As some of our partners are using sitekey feature, we need to investigate if it's possible to implement it in MV3. The idea of this spike is not to implement the feature itself, but understand the complexity of it, find possible solutions which would work for the partners.

Information about Sitekey feature: https://confluence.eyeo.com/display/CT/Sitekeys

First step would be to make sense of the past work:

• Sitekey Alternative

Targeting problem

Figure our the feasibility of having Sitekey feature in MV3 SDK.

Question we are trying to answer

What are the options to implement sitekey feature in MV3 SDK?

What theory/solution are we trying to test?

1. Sitekey Alternative - current proposal.

Please link any other ideas which are tested.

Success/failure criteria

Sitekey feature feasibility is clarified outlining all the changes to the current implementation.
