Nginx – Using HTTP2
There goes a lot more behind the scenes between a browser and a server than we might think. Our browser may be handed a index.html but on processing, it (the browser) may need to get additional documents such as style sheets, JavaScript files, etc. This requires multiple connections to the server. Making a connection requires performing the TCP three-way handshake, exchanging headers, etc. all of which introduces unnecessary overhead, as well as latency to the client. It is in this context that the need for a better way to serve documents become apparent.
It wasn’t until the publication of the HTTP/2 protocol that the issue could be solved. HTTP/2 protocol, officially RFC 7540 or more recently RFC 9113, is a replacement for the older HTTP/1.1 which provides an optimized method for transportation of documents over TCP. It allows multiplexing connections so that multiple documents can be sent over the same stream. It also allows compressing the headers and many requests into a single packet. Furthermore, it provides an optional feature called server push whereby a server can send additional documents that the client may need along side the response for the document that was actually requested. For example, a server may send the style sheets and JavaScript files along side the response for the request to an HTML file.

How to Install Latest Linux Kernel in RHEL 8

Since a Kernel is the primary bridge of communication between the hardware and software components of an entire computer system, it is responsible for such a system’s integrity and supported hardware compatibility. Also, it is the kernel that provides an interfacing link between system processes and computer hardware.
