Abstract
Techniques described herein enable a client to store information indicating whether various hosts (e.g., servers, web domains) support a preferred security protocol, such as a False Start-modified TLS or SSL protocol. The client may then use this information to dynamically determine whether to use the preferred protocol when connecting to a particular host. When the client attempts a handshake to establish a secure connection with a host for the first time, the client does so using the preferred protocol. If the handshake fails, the client locally stores domain or other identifying information for the host so that the client may employ a non-preferred protocol in subsequent connection attempts. Thus, a client may avoid performance degradation caused by attempting a preferred-protocol connection with a host that does not support the preferred protocol. Stored information may include a time stamp enable periodic checks for host capability updates.
