# Riddles Lab Assessment Cory, nice work! We talked through the questions you left in comments. Regarding a few questions in notes: > I think this is the number of characters in the response. Yes--the receiver wants to know that the whole message came through. > I'm not sure what the nginx/1.22.0 means Indeed, nginx is one of the two most common web servers. And from your commit message: > I've seen 404 messages when trying to go to URLs that don't exist, but > I'd not really thought about what it meant or if I could get other numbers > to show up! I just accepted its existence and didn't question if there was > a reason for that particular number. I think this kind of connection between formal CS learning in the classroom and everyday tech-mediated experiences is incredibly important!
