how to use proxy thorugh command line

[ravi.xolve]

I use windows 2000. Here I access Internet through a proxy server with ip like 192.168.34.56 at port 3128. How can I use telnet on command line to access the computer located on the WWW.
e.g.
telnet www.linuxzoo.net

the server on which the site is hosted must actually allow access through telent 4 u 2 b abl to access the site using a telnet client

and telnet being so insecure, such access is permitted rarely by sites
