Hi,
One of my anvil apps is continously getting scanned by bots. From the session logs i see the following:
session started: 2026-03-11 10:21:37.327000

Although i do not use routing, i thought that by adding the following “catch all” routes would help me. But sadly it is not.
@anvil.server.route("/:path", methods=["GET", "POST"])
def catch_all_route(path, **params):
return anvil.server.HttpResponse(404, "Not found")
@anvil.server.http_endpoint("/:path")
def catch_all_api(path, **params):
return anvil.server.HttpResponse(404, "Not found")
Has someone else experienced the same issue, if yes, how did you solve it? 
Preferably i dont want to add user authentication to the app.
