I have been combing through the devtools docs and other resources looking for a means of getting the initiator URL (if available) from all resources loaded on a page. I have tried the performance API, but this only allows one to determine the initiatorType ("css", "script", etc).
I am trying to programmatically determine a resources' "Request Initiator Chain", but so far it seems it is only possible manually via devtools.
Any ideas? Thanks in advance!
