fair enough - if users are prevented to access these WMS layers, there
should be an option that would allow them to access the layers.
Yet another option to the WMS loading dialogue - sigh ...
I know it is already crowded, default should be off (= add dpi parameter)
I created a ticket [1]

Hi all,
I think the dpi parameter is a useful extension and should be added by
the QGIS client (given that the dpi are really correctly detected).
Correct, therefore QGIS adds this parameter in different flavours for
the most common WMS servers (I assume because this parameter is not
defined in the WMS standard as has already been pointed out in this
thread).
If a WMS server chokes on additional paramters it is not very well
designed. They can just ignore these extra parameters if they do not
know how to deal with it.
My problem is not that geoserver chokes on the additional parameters but
that for _some_ layers the geoserver-specific parameter
"format_options=dpi:96" makes it throw an error.
I know that these layers are poorly configured but cannot do anything
against it (because other software depends on them). My users currently
cannot access these layers. Miguel Ángel Castro (who started this
thread) described that he cannot access layers from
http://idecan2.grafcan.es/ServicioWMS/EspNat
Therefore I opt for a configuration option to switch off the dpi
parameter because public servers may be misconfigured and still people
want to display their layers in QGIS.
Bernhard
