in horizon admin page go to servers and edit connection server settings
un-check "Use Secure Tunnel Connection to Machine"
i try this but there is no result , the traffic still non optimized in Riverbed .
The client and agent will still establish an SSL connection through PCOIP. This is not the way to approach your challenge. Riverbed should have documentation on Horizon View and I would work with their support. You may need to get VMware involved as they likely have an approved list of WAN accelerators.
