For a Piwik website or globally, it is already possible to exclude / ignore URL parameters. However, because the default request method is
GET, ignored URL parameters would be still visible in the access log of the Piwik server.
Instead it would be great to be able to have a method in the JS tracker to ignore URL parameters like
_paq.push(['setIgnoreUrlParams', 'sid', 'cid']);. Not sure what a good method name would be.
In the tracker itself we already have a method
removeUrlParameter() to remove a URL parameter so it should be not too hard to develop. We would add this probably to the method
purify(url) where we already modify the URL based on configuration.
@tsteur is this still open? If it is, I would like some guidance as it is going to be my first
