HTTP/2 – Turbo websites
HTTP/2 is the latest version of the internet connection protocol. It was released in 2015. Its advantages over the previous version HTTP/1.1 are as follows:
- Generally shorter latencies: This makes web content load faster.
- Only one communication channel: This avoids unnecessary overhead data and the transmission is faster because there are no longer several data channels. Several data channels also interfered with each other, making transmission slower. With HTTP/2 it is therefore unnecessary to split large files into smaller parts for transmission just to be put back together afterwards. Multiple files can be transferred in parallel without any problems.
- Better compression: With HTTP/2, the header data can also be compressed, so less data needs to be transferred. The header data contains important additional information about the transferred data.
- Prioritization: The web browser can tell the server which data packets should be transferred with higher priority. This allows important website data to be loaded earlier.
- Push from the web server: This allows the web server to send information to the web browser before it has even requested it. This makes the transmission faster because the time for the request from the web browser is eliminated.
HTTP/2 is backward compatible with the previous version, so there are no problems with web browsers that do not support HTTP/2.
