Stating the obvious here, but whats needed is some kind of proxy device
which keeps the session locally alive whilst fighting with the ICA session
of the satellite uplink... isn't there some clever Cisco devices that do
this kind of thing??

Subject: [THIN] Limits of Latency
Hi, list.
Is there any documentation from Citrix or another source that sets a bound
on how much latency an ICA session will tolerate?
I have a few new locations that have recently been set up our WAN/Satellite
guy to use a DirectWay satellite connection to the internet then on into
Nfuse and my MF 1.8 farm. The problem is that these locations experience
frequent disconnects from ICA sessions to the point of rendering Citrix
unusable. (No problems surfing mind you.) A ping from them to us returns
with a latency of 850-1000ms. The best I remember hearing from this list
and elsewhere, latency beyond 300-400ms degrades performance and can cause
disconnects. Is this accurate? What is the max latency tolerance by your
experience?
Also, I have already tweaked the recommended ICA time-out and TCP
retransmission settings with no results for this problem. Is there any
other tweaking that might help?
Thanks in advance,
