Client-Server Encrypted Connection

Encryption impacts performance, both on the server side and the browser side. With HTTP 1.1, avoiding communication encryption made perfect sense. However, with the current availability of browsers that have implemented HTTP/2, it is practically impossible to support HTTP/2 without mandating an encrypted browser-server connection. While this may sound counter-productive, the accelerated performance offered by HTTP/2 is often much greater than the performance penalty of using encrypted connections.

The Internet has evolved significantly since HTTP 1.1 was introduced 17 years ago. During this evolution, we've seen many enhancements to improve a user's online experience, such as the development of rich content. However, delivering these improvements came at one particular cost: performance. These evolving performance challenges were something that HTTP 1.1 was not designed to handle.

In February 2015, the Internet Engineering Task Force (IETF), an international community of network designers, operators, vendors and researchers concerned with the evolution of Internet architecture, released a new HTTP/2 version to address those challenges and adapt to the progression that Internet content has undergone.

As HTTP/2 took a long time to arrive, many interim best practices were developed to bypass the performance bottlenecks of HTTP 1.1. However, we learned that many of those HTTP 1.1 performance-enhancing practices would actually contribute to slowing web application delivery rather than accelerating it when using the new HTTP/2 protocol. In this slideshow, Radware's Yaron Azerual takes a look at a few examples organizations should consider.
