| 137 The following explanation of HTTP serves to guide you through the | |
| 138 code as well as to expose any misunderstandings I may have about | |
| 139 HTTP (so you don't need to read the code to figure out I'm wrong | |
| 140 :-). | |
| 141 | |
| 142 HTTP (HyperText Transfer Protocol) is an extensible protocol on | |
| 143 top of a reliable stream transport (e.g. TCP/IP). The protocol | |
| 144 recognizes three parts to a request: | |
| 145 | |
| 146 1. One line identifying the request type and path | |
| 147 2. An optional set of RFC-822-style headers | |
| 148 3. An optional data part | |
| 149 | |
| 150 The headers and data are separated by a blank line. | |
| 151 | |
| 152 The first line of the request has the form | |
| 153 | |
| 154 <command> <path> <version> | |
| 155 | |
| 156 where <command> is a (case-sensitive) keyword such as GET or POST, | |

| 2887 | 167 |
| 168 Similarly, for output, lines ought to be separated by CRLF pairs | |
| 169 but most clients grok LF characters just fine. | |

| 174 | |
| 175 (i.e. <version> is left out) then this is assumed to be an HTTP | |

179 The reply form of the HTTP 1.x protocol again has three parts: |

198 a request SPAM will be handled by a method do_SPAM(). If no |
| 2887 | 199 such method exists the server sends an error response to the |
| 200 client. If it exists, it is called with no arguments: | |
| 201 | |
| 202 do_SPAM() | |
| 203 | |
| 204 Note that the request name is case sensitive (i.e. SPAM and spam | |
| 205 are different requests). | |
| 206 | |
| 207 The various request details are stored in instance variables: | |
| 208 | |
| 209 - client_address is the client IP address in the form (host, | |
| 210 port); | |
| 211 | |
| 212 - command, path and version are the broken-down request line; | |
| 213 | |
| 214 - headers is an instance of mimetools.Message (or a derived | |
| 215 class) containing the header information; | |
| 216 | |
| 217 - rfile is a file object open for reading positioned at the | |
| 218 start of the optional input data part; | |
| 219 | |
| 220 - wfile is a file object open for writing. | |
| 221 | |
| 222 IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING! | |
| 223 | |
| 224 The first thing to be written must be the response line. Then | |
| 225 follow 0 or more header lines, then a blank line, and then the | |
| 226 actual data (if any). The meaning of the header lines depends on | |
| 227 the command executed by the server; in most cases, when data is | |
| 228 returned, there should be at least one header line of the form | |
| 229 | |
| 230 Content-type: <type>/<subtype> | |
| 231 | |
| 232 where <type> and <subtype> should be registered MIME types, | |
