Experiments
1. Connect via telnet to port 80 of the server thalia.spec.gmu.edu.
Construct a HTTP request that uses the POST method to send
form input to the URL /˜pparis/cgi-bin/test.cgi. Specifically, em-
ulate the request that a browser would send to indicate that the
form field “name” has been set to “Bobo.” Turn in the request
that you sent together with any explanations you deem necessary.
Hint: Read RFC 2616 (HTTP/1.1) to learn how to send a request
with a message body. Sections 9.5, as well as 4.3-4.4 should be
most relevant.
2. Connect via telnet to port 80 of the server. Construct an HTTP
request that allows you to retrieve the password protected file
/˜pparis/secret/secret.html. The username is “Aladdin” and the
password is “open sesame” for that file. Turn in the request that
you sent together with any explanations you deem necessary.
Hint: Read section 11 of RFC 2068 (even though RFC 2068 has
been obsoleted by RFC 2616, it is easier to read the older RFC
since the material on authentication has been delegated to yet
another RFC in 2616).
