We were told the same thing by our Riverbed rep as well.

From memory I dont believe Riverbed accelerators dont support Citrix
ICA type protocols due to the way they work.
We had a riverbed consultant here the other day talking about them and
he advised forget it if you want to use ICA over it, it just passes is
through. the Riverbed Accelerators are more of a disassembler/assembler
and do pattern matching on the traffic comming through then reconstruct
the traffic at the recieving end. They work very well on normal
streaming type data such as SMB, SQL etc but for other traffic such as
ICA apparently it just passes it through and cant do anything with it.

Timely topic.  I just found out that we are installing Riverbed
Accelerators.  Anyone using these?

        Which product are you looking at?  Expand, for example, claims
300%-400% acceleration for ICA traffic.  Some Citrix SEs are seeing a
slight bump in performance by piping ICA traffic through the
NetScaler...   No word on WanScaler yet.

        Is anyone familiar with WAN Accelerators? One of our network
engineers is going to begin testing this out. We have offices in North
America and overseas in Europe. I can understand why he would want to
use something like this. However because we already use Citrix for most
of our overseas remote access I am doubting if perhaps the 2
technologies will play together nicely or at all and perhaps even
confilct. If ICA packets are already wrapped, efficient and without real
data being passed across the WAN because only mouse and key strokes as
well as screenupdates are being passed I don't see how a WAN accelerator
will do much for us. There may be some need to directly access intranet
or some direct file access outside of Citrix in which case the WAN
Accelerator concept would make sense via the specialized caching of data
being employed by this new technology. How have people found the
performance of WAN Accelerators as well as stability and other issues
that may be occuring? And will there be issues for ICA packets being
"accelerated" or as with packetshaping would special priorities and
exceptions have to be made?
