What status code did the server send back? 304 Not Modified What HTTP method did the browser use to make the request? GET What is the request path? /shows/82/episodes What is the first line of the response body? [ What is the value of the response header called "Content-Type" ? There was no header called content-type. So when I told this AI, it explained sometimes the "Content-Type" header might not be visible in the headers, especially for JSON responses. So if you see the response starting with [ (an opening square bracket), it's a good indication that the "Content-Type" is “ application/json”. What is the value of the request header called "User-Agent"? Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36
