This blog post from Netscout was very informative. I learned quite a bit about D/TLS and how it related to "Citrix Netscaler Application Delivery Controllers (ADCs)". I am always interested in server tuning or configuration tips.
if you have a Citrix Netscaler environment, take a minute or two and check out the article since "Approximately 4,283 abusable D/TLS servers have been identified to date."
