Microsoft has announced some upcoming changes to Edge's handling of both encrypted and unencrypted traffic. Changes will speed up connections and lead to lower latency.
These changes will come to Edge via the builds by Windows Insider and will be added to Edge core, the EdgeHTML engine, from version 14,14361 onwards.
The first of these new features will be support for TLS 1.3, the latest version of the Transport Layer Security (TLS) protocol. The TLS 1.3 was announced last January, and is expected to be released this summer.
TLS 1.3 is a simple upgrade to the most popular web encryption engine, and Microsoft seems to be hurrying to adopt it.
Unfortunately, all TLS connections require three roundtrips between the client and the server to create secure connections. Two roundtrips are for creating the TLS connection, and the latter is for the TCP connection. Here's where it comes to help TLS False Start and TCP Fast Open.
TLS False Start is an extension of the TLS protocol that allows connections to be initiated Mission of encrypted data after the first TLS roundtrip between client and server. This reduces one of the two TLS roundtrips.
TCP Fast Open is an extension of the TCP protocol that uses an encrypted cookie stored on the client to control identity on subsequent connections to a server. This allows future TCP connections to reduce the required TLS roundtrips.
As mentioned above, the new features will be seen in Edge (Insiders will have it first) from build 14.352 onwards.
