RE: issue-25

Hi Ronan,

 

I had another thought about frequency capping. If you use the
ETag/If-None-Match to contain a low entropy count value, 0..7, you could
combine that with the If-Modified-Since header to give you unique visitor
detection *and* frequency counting, without a persistent UID in a cookie or
anywhere else,  and without JS. 

 

You could do that in your 1x1 gif handler and not need the iframe (or the
v60.js script tag that I notice imrworldwide.com - a Nielsen domain,  uses
sometimes).

 

If you did that (in the DNT:1 case), you would not need a permitted use.

At least for some of our products, yes we use the campaign_id and
creative_id as URL parameters.  These might be distributed in the pixel URL
by the ad agency, or they might be macros (%CREATIVE) that are part of the
ad network software.  There are many variations as to how that information
is inserted.

How do you do it now? With a 1x1 gif? How do you get the copy of the ad
network's ad identifiers (Kathy called them campaign_id & creative_id). I
assume they must be in the url parameters if you cannot use JS.
