Just to make sure, I want to repeat that a technical definition of 1st 
and 3rd party is not necessarily the same as a legal definition nor is 
it a definition that resembles what a user perceives to be intended/not 
intended interaction.

A legal definition is connected to the use of data. In the context of 
OBA it is connected with the use of data across sites. The use of data 
across sites is in many cases not transparent at all to the user.

Just quoting a sentence will likely distort the true meaning of the 
passage in WP171.
The full quote of the relevant paragraphs is therefor:

"As recently pointed out by the Article 29 Working Party28, whether a 
publisher can be
deemed to be a joint controller with the ad network provider will depend 
on the conditions of
collaboration between the publisher and the ad network provider. In this 
context, the Article
29 Working Party notes that in a typical scenario where ad network 
providers serve tailored
advertising, publishers contribute to it by setting up their web sites 
in such a way that when a
user visits a publisher's web site, his/her browser is automatically 
redirected to the webpage
of the ad network provider. In doing so, the user's browser will 
transmit his/her IP address to
the ad network provider which will proceed to send the cookie and 
tailored advertising. In
this scenario, it is important to note that publishers do not transfer 
the IP address of the visitor
to the ad network provider. Instead, it is the visitor's browser that 
automatically transfers such
information to the ad network provider. However, this only happens 
because the publisher has
set up its web site in such a way that the visitor to its own web site 
is automatically redirected
to the ad network provider web site. In other words, the publisher 
triggers the
transfer of the IP address, which is the first necessary step that will 
allow the subsequent
processing, carried out by the ad network provider for the purposes of 
serving tailored
advertising. Thus, even if, technically the data transfer of the IP 
address is carried out by the
browser of the individual who visits the publisher web site, it is not 
the individual who
triggers the transfer. The individual only intended to visit the 
publisher's web site. He did
not intend to visit the ad network provider's web site. Currently this 
is a common scenario.

Taking this into account, the Article 29 Working Party considers that 
publishers have a
certain responsibility for the data processing, which derives from the 
national implementation
of Directive 95/46 and/or other national legislation29. This 
responsibility does not cover all
the processing activities necessary to serve behavioural advertising, 
for example, the
processing carried out by the ad network provider consisting of building 
profiles which are
then used to serve tailored advertising. However, the publishers' 
responsibility covers the first
stage, i.e. the initial part of the data processing, namely the transfer 
of the IP address that
takes place when individuals visit their web sites. This is because the 
publishers facilitate
such transfer and co-determine the purposes for which it is carried out, 
i.e. to serve visitors
with tailored adverting. In sum, for these reasons, publishers will have 
some responsibility as
data controllers for these actions. This responsibility cannot, however, 
require compliance
with the bulk of the obligations contained in the Directives."

Kind regards,
Rob (speaking for himself)
