| 138 The following explanation of HTTP serves to guide you through the | |
| 139 code as well as to expose any misunderstandings I may have about | |
| 140 HTTP (so you don't need to read the code to figure out I'm wrong | |
| 141 :-). | |
| 142 | |
| 143 HTTP (HyperText Transfer Protocol) is an extensible protocol on | |
| 144 top of a reliable stream transport (e.g. TCP/IP). The protocol | |
| 145 recognizes three parts to a request: | |
| 146 | |
| 147 1. One line identifying the request type and path | |
| 148 2. An optional set of RFC-822-style headers | |
| 149 3. An optional data part | |
| 150 | |
| 151 The headers and data are separated by a blank line. | |
| 152 | |
| 153 The first line of the request has the form | |
| 154 | |
| 155 <command> <path> <version> | |
| 156 | |
| 157 where <command> is a (case-sensitive) keyword such as GET or POST, | |

| 2887 | 168 |
| 169 Similarly, for output, lines ought to be separated by CRLF pairs | |

199 a request SPAM will be handled by a method do_SPAM(). If no |
| 2887 | 200 such method exists the server sends an error response to the |

| 204 | |
| 205 Note that the request name is case sensitive (i.e. SPAM and spam | |
| 206 are different requests). | |
| 207 | |
| 208 The various request details are stored in instance variables: | |
| 209 | |
| 210 - client_address is the client IP address in the form (host, | |
| 211 port); | |
| 212 | |

| 223 IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING! | |

| 225 The first thing to be written must be the response line. Then | |

| 227 actual data (if any). The meaning of the header lines depends on | |
