#  Important: It is helpful to send the contents of the
#  ssh.LastErrorText property when requesting support.

#  Open a direct-tcpip channel.  We want the SSH server to connect
#  to www.chilkatsoft.com, port 80 (i.e. the web server).
#  Data sent through the SSH tunnel is forwarded to the remote
#  host:port.  (Note: The remote host:port does not need to be
#  a web server.  It can be anything.  It can be your own
#  customer application server that listens on a port, or any
#  other type of server.)
#  When we read from the SSH channel, we'll be reading data
#  sent from the remote host:port (i.e. the web server in this
#  example).

#  Get the HTTP response.
#  First read the HTTP response header which ends with a double CRLF.
#  Calling ChannelReceiveUntilMatch will receive until match string is seen,
#  or until a timeout occurs (IdleTimeoutMs property).  ChannelReceiveUntilMatch
#  may read beyond the match string, but it will stop reading as soon as the match
#  string is seen.

#  Now get the body of the HTTP response (this is the HTML content
#  of http://www.chilkatsoft.com/xyz.html
#  It's possible we've already received the entire HTTP response in the
#  call to ChannelReceiveUntilMatch.  Therefore, we'll poll for any remaining data
#  and wait a max of .2 seconds.

#  We're not checking for an error here.
#  A return value of -2 means that no data was available and the poll simply timed out (not an error)
#  A return value of -1 indicates an error.
#  A return value greater than 0 indicates that additional data was received.

$("---- HTML BODY ----")

#  Extract the remainder of the accumulated data in the internal receive buffer.
#  This should be our HTML body:

$htmlBody = $ssh.GetReceivedText($channelNum,"ansi")
$($htmlBody)

#  Close the channel:
$success = $ssh.ChannelSendClose($channelNum)
if ($success -ne $true) {

#  Disconnect
