![### HTTP responses have:
- a status code (200 OK! 404 not found!)
- headers
- a body (HTML, an image, JSON, etc)
### Here's the HTTP response from `examplecat.com/cat.txt`:
```
HTTP/1.1 200 OK
status
Accept-Ranges: bytes
Cache-Control: public, max-age=0
Content-Length: 33
Content-Type: text/plain; charset=UTF-8 Date: Mon, 09 Sep 2019 01:57:35 GMT
Etag: "ac5affa59f554a1440043537ae973790-ssl"
Strict-Transport-Security: max-age=31536000
Age: 0
Server: Netlify

```
The first line, `HTTP/1.1 200 OK` is the status code. "200" is the status.
The lines from `Accept-Ranges` to `Server` are the headers.
The cat picture is the body.
### There are a few kinds of response headers:
- when the resource was sent/modified:
```
Date: Mon, 09 Sep 2019 01:57:35 GMT
Last-Modified: 3 Feb 2017 13:00:00 GMT
```
- about the response body:
```
