How can I delete all resources in CalDAV calendar collection

[monkeyfdude]

• I am not a sabre/dav user yet.

• I am trying to delete all resources in CalDAV calendar collection

• I use curl -k --user "user1:pwd1" -X DELETE -H "Content-Type: text/calendar; charset=utf-8" "http://example.com:8008/calendars/users/user1/calendar/

• I see the all the resources removed and calendar collection not accessible anymore

• But, when I try to create an event again using "PUT", I get error code 409

• I even tried re-creating that account like a new account.

• Would you be able to tell me the right way to delete all resources in a calendar collection?
