Over the next 12 months, Salesforce is preparing to disable TLS 1.0 encryption in a phased approach to prevent it from being used to access the Salesforce service during inbound and outbound connections.
How does this impact my existing Flex and Air applications that communicates with Salesforce?
Or there is no impacts?
So far, I have found below information, but I am not 100% certain it’s supported:
I figured out my answer.
Our flex applications are supported (Flex SDK 4.5)
I have contacted Salesforce support, with given test URL https://tls1test.salesforce.com/, callout URL request returns positive.
Note that Internet Explorer advanced settings TLS support has to be turned on, if they are turned off, the call out to above test url will return negative.
