I just checked my server logs and found the following weird requests coming in quite a lot. I have iOS 9 Universal Linking implemented, but those requests are running against /apple-app-site-association as far as I know.

Jan 15 09:36:23 method=GET path="/.well-known/apple-app-site-association"

Has anyone else seen these patterns? Is this some known spamming or something?

i believe iOS 9.3 introduced slightly different lookup logic around the apple-app-site-association file and the app handoff feature.

"Handoff first searches for the file in the .well-known subdirectory (for example, https://example.com/.well-known/apple-app-site-association), falling back to the top-level domain if you don’t use the .well-known subdirectory."

see: https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/Handoff/AdoptingHandoff/AdoptingHandoff.html#//apple_ref/doc/uid/TP40014338-CH2-SW10
