New iteration of HTTP protocol brings more challenges than previous upgrades. We now need the UDP transport and need to implement a different negotiation method, another trouble is the need for embedded security/encryption. You will learn how to implement this protocol in the network, and most importantly - why.

Plan:
- Protocol history: HTTP/1, HTTP/1.1, SPDY, HTTP/2
- Main differences of QUIC and HTTP/3
- UDP
- Encryption
- Connection ID
- Protocol negotiation
- Use of HTTP/3 in real networks
- All the boxes in between of client and server
- Implementation in NGINX
- Conclusions and questions
