I try to protect the call of a webcal address with a login. Basically it is clear to me how to protect a directory with .htaccess and basic authentication. But what about the protocol "webcal" and parameters in the URL?
Specifically, I want to protect only this URL:
webcal://domainname.com/index.php?option=com_jevents&task=icals.export&format=ical&catids=0&years=0&pk=04575786497458993643754733455&i=215
Does anyone have any ideas? Thanks!
