What is HTTP/2?
Before we dive into the error, it’s essential to understand the protocol that’s causing the issue. HTTP/2, also known as H2, is the second major version of the Hypertext Transfer Protocol (HTTP). It was designed to improve the performance and efficiency of web communication by introducing multiple enhancements.
Binary Framing: One of the significant upgrades in HTTP/2 is the use of binary framing, which allows multiple requests and responses to be multiplexed over a single connection. This eliminates the need for multiple connections and reduces the overhead associated with traditional HTTP/1.1.
<strong/Header Compression: HTTP/2 employs header compression to reduce the size of header data, resulting in faster page loads and improved performance.
Server Push: Another notable feature of HTTP/2 is server push, which enables servers to proactively send resources to clients, reducing the number of requests and improving page load times.
