The requests dataset contains the request/response HAR payload for each request. For example the JSON path $.response.headers may include Set-Cookie headers. I’m looking for examples to show, but finding results like {name: "Set-Cookie", value: "[110 bytes were stripped]"} which aren’t very useful.
I found a related comment:
@patmeenan is there still an issue with capturing cookies in Chrome? This would be really detrimental to the Cookies chapter we’re planning for the Web Almanac.
