Associate third-party domains with first-party with grace period

[cbuijs]

To fix some sites, we need to allow some of third-party domains for that particular site. Actually to allow ads for example to see news-videos (ABC, NBC, etc).

As we cannot determine if a domain is actually third-party to a site, we might maybe want to "associate" domains in a configuration/syntax like:

<first.party.domain> <third-part-domain> [ttl]

Where:

<first.party.domain> is the site in question.
<third.party-domain> is associated.
[ttl] the time in seconds to allow/grace the third-party-domain. Optional, when not specified the ttl of the first-party-domain (not third!) is taken. This means it will take the starting time of the first-party-domain and count down from that time. Not actually the starting time of the third-party as the first-party should be leading.

Example:

nbc.com doubleclick.net 300

Just an idea to make sure when whitelisting we limit the amount of "garbage" coming in.

We maybe want to call this "greylisting" (or graylisting)
