# See Global Unlock Sample for sample code.

set ssh [new_CkSsh]

# To connect through an HTTP proxy, set the HttpProxyHostname
# and HttpProxyPort properties to the hostname (or IP address)
# and port of the HTTP proxy.  Typical port numbers used by
# HTTP proxy servers are 3128 and 8080.
CkSsh_put_HttpProxyHostname $ssh "www.my-http-proxy.com"
CkSsh_put_HttpProxyPort $ssh 3128

# Important:  Your HTTP proxy server must allow non-HTTP
# traffic to pass.  Otherwise this does not work.

# Connect to an SSH server via an HTTP proxy:

# Hostname may be an IP address or hostname:
set hostname "192.168.1.108"
set port 22

# Your application is now connected to an SSH server 
# through an HTTP proxy.
