I recently stumbled across a series of HTTP posters that detail aspects of the protocol in an easy to read manner. If ever need to look up something quickly check this out then.

There are 3 different posters;

  • Status-Codes
  • Methods
  • Headers
  • HTTP requests and responses generally each consist of two parts: a body and a block of headers. HTTP headers are listed as key-value pairs, with a header name and a
    header value. Headers are used to contain metadata about the request or response.
