Cloudflare already supports the HTTP/3 protocol, which is already included in the Chrome Canary και θα προστεθεί σύντομα στο Firefox Nightly. Το νέο πρότυπο θα κάνει την περιήγησή μας στο Διαδίκτυο πολύ πιο γρήγορη και πιο safe.
Let's take the things from the beginning:
Τα προγράμματα περιήγησης, οι διακομιστές ιστού (web servers) και άλλες υπηρεσίες της υποδομής του διαδικτύου αρχίζουν να υποστηρίζουν ένα νέο πρότυπο που ονομάζεται HTTP/3. Το συγκεκριμένο πρωτόκολλο χρησιμοποιεί το QUIC. Πρόκειται για μια πιο σύγχρονη version of HTTP, which browsers use to communicate with servers and send or receive data.
HTTP/3 has been rewritten from the ground up for faster sending data and for better error handling. It also has built-in encryption.
This means more speed and safety. Of course the average user of the process doesn't need to know anything about HTTP / 3 and QUIC. But webmasters and developers will be busy the next day, until one day, the browsers and websites you use will start communicating via HTTP / 3.
The original version of HTTP uses the Transmission Control Protocol (TCP). It was first mentioned in 1974, but was never designed to be a fast data transfer protocol. Google tried to fix many of the problems TCP presented with a new protocol called SPDY, which it used in HTTP / 2.
HTTP/2 became widely available in late 2015, with features such as compression data and adding multiple requests to a single TCP connection to speed things up a bit.
Since September of 2019, W3Techs reports that HTTP / 2 is currently used by 41% of websites.
HTTP / 3 now, in addition to being rewritten from the beginning, instead of using TCP, uses Google's QUIC protocol.
HTTP / 3 was originally known as HTTP-over-QUIC and includes TLS 1.3 encryption.
Το QUIC (Quick UDP Internet Connections) σχεδιάστηκε για να είναι ταχύτερο με χαμηλότερη καθυστέρηση από το TCP. Σε αντίθεση με το TCP, ένα σφάλμα όπως την απώλεια ενός μικρου μέρους δεδομένων δεν θα προκαλέσει τη διακοπή της σύνδεσης αλλά η σύνδεση θα συνεχίσει και θα προσπαθήσει να επιδιορθώσει το πρόβλημα. Το QUIC θα συνεχίσει να μεταφέρει άλλα δεδομένα ενώ προσπαθεί παράλληλα και την resolution of the problem.
QUIC has been added to Google Chrome by 2013, and the browser uses it when communicating with other Google services or some other sites such as Facebook. However, QUIC does not yet exist as a template built into other browsers. With HTTP / 3 technology we will soon see it in other browsers.

Good evening.
As for Chrome Canary, do we need to make some adjustments to enable HTTP / 3?
