Appendix 1: HTTP and Conditional GET Message Syntax

Note that when using Telnet to connect to port 80, you must remember that HTTP was designed as a protocol for machine-to-machine communication. Because a carriage return by itself is interpreted as the end of a command stream and the connection is usually set up to close after executing one command stream, sending an extra return will usually terminate your Telnet session. Additionally, characters are not echoed by the destination server. The specification of HTTP is covered in RFC 2616, which is available by one of the methods you've already used this semester.

Note also that where command words are shown below as all capitals they must be typed this way, not all lower case or mixed case.
HTTP Request Message

Syntax:
request line::[method] [URL] [HTTP version]
header line:: [tag]: [value]
...
{extra carriage-return line feed}

There is one request line and as many header lines as needed.

An example request follows. What you type is in bold, but you should replace such things as the directory name and the filename with appropriate entries.
