HTTP/2 increases your page’s performance by speeding up the data transfer speed. Your web and mobile users will be able to access your services faster. Also; you can increase the security of your websites with the SSL feature, and obtain positive results in terms of criteria also.
What is it?
HTTP/2 was released in 2015 as a major revision to the HTTP protocol. It is derived from the SPDY protocol that enables faster page load times and reduced server-client Round Trip Times.
HTTP/2 uses a single connection to load a website: Only a single TCP session for each connection is made, this reduces the number of Round Trips made between the server and the client to keep the TCP connection authenticated. So a single TCP connection that HTTP2 utilizes significantly reduces the latency.
HTTP/2 allows sending multiple requests simultaneously on the same connection and this feature is called multiplexing. Multiplexing reduces latency as each server request is not queued as in HTTP1.1, another packet via the same TCP connection can be requested without waiting for the completion of each data packet transfer.
HTTP/2 also has Server Push compatibility; via this feature additional resources can be sent to the client for future and immediate use. This way, specific content on your page is also pushed to the client for use without waiting for other connections, so your pages work faster as immediate content is also pushed from the server.
