Answering again since we need to move on. My current feeling: * Using a new action or passing a parameter to identify a query that shouldn't be logged (through a URL parameter) sounds the same kind of complexity to me. * That said I'm +0 for a new view action (I hope there are no other actions required though) * I keep maintaining that the need to not log something should be independent of the action called and thus even if we had a new action we can also add a URL parameter to prevent stats logging. "logstats=0|1" sounds good to me. We could easily make the new view action set the parameter. * Re the question on how the stats code will get access to that parameter, yes, it could be put in the context (it could be retrieved from the request URL but it' not a good idea to become dependent on the environment). * I'd be +0 to reuse the ajax param too although in the longer run I'd prefer to introduce a "logstats" param since not wanting to log some stats shouldn't be related to ajax specifically. It's a more general use case. WDYT?
