The following url https://planning.univ-st-etienne.fr/jsp/custom/modules/plannings/anonymous_cal.jsp?resources=3797&projectId=1&calType=ical&firstDate=2017-08-22&lastDate=2018-08-20 automatically downloads a file for me (.ics) which I need its text content. I would like to automatically get this text by code for my website so I don't need to update it manually everyday.
How could I manage that?
