Does either RiverBed "Steelhead" or Expand Networks optimization tools support secure Citrix and if so how do they compare?

Thanks. We'll let you know when a new response is added.

By it’s nature the data patterns will have been scrambled by the encryption mechanisms, and the pattern matching algorithms used by both Expand and Riverbed will have no effect. However, if the encryption in the ICA sessions can be set to low/basic then the byte level caching mechanism of the Expand devices, along with Expand’s Citrix specific plug-in, will be able to realize a compression ratio of around 5:1. The Riverbed units that I’ve seen in the field don’t handle ICA traffic particularly well, and certainly don’t have the same focus on real time traffic as Expand.

    If you would like to otherwise compare the two WAN optimization vendors, you can look at this tutorial that highlights how Expand Networks and Riverbed Steelheads work.

    Disreguard the above comment and do your own research on Riverbed ICA. http://blog.riverbed.com/2010/09/index.html Riverbed: *Does NOT require golbal disabling of compression or encryption on the XenApp servers. *Does do per ICA channel QOS. I.e Display and keyboard traffic can have a higher priority than print jobs and file transfers WITHIN THE ICA PROTOCOL. *Is implemented with a single checkbox within the RIverbed interface to optimize ICA
