HTTP/2

HTTP/2 is the updated version of the HTTP communications protocol used by the web. HTTP/2 has several benefits over HTTP/1.1, including the ability for browsers to accept more content from a website’s server at once, which improves website performance.


Use modern protocols for improved performance.


All modern websites should take advantage of the performance benefits in HTTP/2, which was specifically designed to work with newer, resource-heavy websites.


page load time

Achieve faster page load times.

HTTP/2 has several features which lead to faster page load times, including the ability for multiple resources to be loaded at once. Sites that use HTTP/2 have been proven to have faster load times than both HTTP/1.1 and SPDY.

IP blocking

Improve your security with HTTPS.

Modern browsers only support HTTP/2 when encrypted with HTTPS, meaning you will need to have a SSL Certificate to utilize HTTP/2. This improves website security and visitor trust. section.io provides SSL Certificates for all users.

website performance

Simple to implement.

With section.io you can use HTTP/2 for browser connections even if your origin servers do not yet support it. The connections between section.io and your origin server can continue to use HTTP/1.1 regardless of the protocol the browser is using.

block attacks

Serve content from one domain.

Websites still using HTTP/1.1 often use multiple connections to get web content or “shard” content so that it is served from secondary domains. With HTTP/2 all content can be served from your primary domain.

Get an all-in-one solution with section.io.


section.io provides all users with HTTP/2 and the necessary SSL Certificates for no extra charges, meaning everyone can take advantage of the performance benefits that come with this updated protocol. section.io provides several other performance improvements built into the platform, including Anycast DNS Hosting, dynamic caching and static caching, and a global cloud network.

section.io also provides developers the ability to test before deployment and immediately identify issues via log management and real-time metrics, meaning that websites using section.io cache more content, scale faster, and block more threats than with any other solution.

HTTP/2: Technical Details


Some of the technical differences with HTTP/2 which lead to better performing websites include:

HTTP/2 will transfer multiple resources concurrently on a single connection. This reduces the TLS/TCP handshake cost traditionally involved with the browser establishing multiple connections to your site and also removes the need to implement domain-sharding to bypass the per-domain connection limits imposed by the browser.

HTTP/2 uses binary-encoding and header compression and when these are combined with the above multiplexing, the typical delays from having many small resources are significantly reduced. The decision to implement image spriting and/or JavaScript and CSS concatenation becomes much more a question of browser cache-invalidation patterns instead of the number of requests required.

Many of the featues in the HTTP/2 protocol are focused on improving the browser experience. The connections between the section.io platform and your origin server can continue to use HTTP/1.1 regardless of the protocol the browser is using.
