I have a ten-years old Chrome extension that was reading cookie header 'Set-Cookie' directly from the HTTP response. Now, am reusing the same extension, however, it does not read any cookie using the same 'Set-Cookie' header. Surprisingly, I debugged and printed all the headers and 'Set-Cookie' is missing. Probably, web servers sets cookies differently now. How can I extract cookies from the HTTP response using the chrome.webRequest.onHeadersReceived Chrome API? What is the cookie header name?
