    ICA and McAfee Web Gateway "The SSL handshake could not be performed" "SSL routines:SSL23_GET_CLIENT_HELLO"


      Hi All,


      When a pc has the proxy configured within the webbrowser and they want to go to access a published application on a Citrix Web Interface (internal adres) they receive the following message.


      "Unable to launch your application. Contact your help desk with the following information: Cannot connect to the Citrix XenApp server. Protocol Driver error."


      SSL Scanning is turned on by default.

      When I turn of SSL Scanning, ICA is working. So the problem has something to do with SSL Scanning.


      Some tracing log entries:


      10:34:16.483: Accepted connection on from

      10:34:16.484: Received 193 bytes


      CONNECT HTTP/1.0



      Connection: Keep-Alive

            Handshake failed

            The SSL handshake could not be performed.

            <b>Host: </b><br />

            <b>Reason: </b>error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol







      Who has the solution?
