Assuming you want to view the raw HTTP response from a Web page at http://www.yourdomain.com/index.html you can use the following telnet syntax (example from dos prompt, note the '.' blank line).
telnet www.yourdomain.com 80
GET /index.html
host: www.yourdomain.com
.
Note that this does not support NTLM with IIS servers for those enterprise users.
