Akamai Technologies announced that it is now "..actively working with more than 150 customers to deliver HTTP/2-enabled websites and is expanding its HTTP/2 program to all customers using qualifying products to deliver TLS encrypted web content.
HTTP/2 represents the first major update to the HTTP network protocol in nearly 20 years. Although websites have dramatically evolved during this time, HTTP, the underlying protocol of the Web, has not. Through features and capabilities such as multiplexing and concurrency, header compression, server push, support for the latest cipher suites, and an overall reduction in development complexity, HTTP/2 is intended to significantly improve the performance and security/privacy of today’s Web.
More than 70 percent of requests on Akamai’s CDN currently come from HTTP/2 compliant browsers; however, some older browser versions will continue to be used for the foreseeable future. Therefore, Akamai’s implementation of HTTP/2 has been designed to use real-time network and end-user intelligence to dynamically apply the appropriate performance optimizations to ensure the best performance for each user. In addition, we believe Akamai is well positioned to offer the tools and intelligence required to take full advantage of the move to HTTP/2. For example, easy‑to‑use, self-service and highly granular configurability allows customers to control the deployment of HTTP/2, while built-in monitoring and reporting helps measure the impact"
HTTP/2 attempts to solve many of the shortcomings and inflexibilities of HTTP/1.1. Its many benefits include:
- Multiplexing and concurrency: Several requests can be sent in rapid succession on the same TCP connection, and responses can be received out of order - eliminating the need for multiple connections between the client and the server
- Stream dependencies: the client can indicate to the server which of the resources are more important than the others
- Header compression: HTTP header size is drastically reduced
- Server push: The server can send resources the client has not yet requested
