Noscript is executed if a browser has no javascript enabled. Currently there is no browser used on the marked without JS but there are blocking addons out there. BUT: Not all of those blocking addons respect the noscript tag. So it`s more or less a “maybe” fallback for old browsers.
Got it, thank you. Would it be wise for me to display the contents of noscript with http or https depending on the protocol of the page request? Otherwise, I think there is the possibility of browser warnings?
Yeah if you have piwik in a subdir the relative methode is the best one. I for myself have one piwik server for a dozends of projects on a other domain. But This domain has a valid SSL Cert so i use a static https:// in the noscript part.
