| 6 | * An HTTP request. | |
| 7 | * <p> | |
| 8 | * From <a href="https://en.wikipedia.org/wiki/HTTP#Request_syntax">Wikipedia</a> | |
| 9 | * </p> | |
| 10 | *<p> | |
| 11 | * A client sends request messages to the server, which consist of: | |
| 12 | *</p> | |
| 13 | * <ul> | |
| 14 | * <li> | |
| 15 | * a request line, consisting of the case-sensitive request | |
| 16 | * method, a space, the requested URL, another space, the | |
| 17 | * protocol version, a carriage return, and a line feed, e.g.: | |
| 18 | * <pre> | |
| 19 | * GET /images/logo.png HTTP/1.1 | |
| 20 | * </pre> | |
| 21 | * </li> | |
| 22 | * | |
| 23 | * <li> | |
| 24 | * zero or more request header fields (at least 1 or more | |
| 25 | * headers in case of HTTP/1.1), each consisting of the case-insensitive | |
| 26 | * field name, a colon, optional leading whitespace, the field | |
| 27 | * value, an optional trailing whitespace and ending with a | |
| 28 | * carriage return and a line feed, e.g.: | |
| 29 | * | |
| 30 | * <pre> | |
| 31 | * Host: www.example.com | |
| 32 | * Accept-Language: en | |
| 33 | * </pre> | |
| 34 | * </li> | |
| 35 | * | |
| 36 | * <li> | |
| 37 | * an empty line, consisting of a carriage return and a line feed; | |
| 38 | * </li> | |
| 39 | * | |
| 40 | * <li> | |
| 41 | * an optional message body. | |
| 42 | * </li> | |
| 43 | * In the HTTP/1.1 protocol, all header fields except Host: hostname are optional. | |
| 44 | * </ul> | |
| 45 | * | |
| 46 | * <p> | |
| 47 | * A request line containing only the path name is accepted by servers to | |
| 48 | * maintain compatibility with HTTP clients before the HTTP/1.0 specification in RFC 1945. | |
| 49 | *</p> | |
