HTTP/2 (originally named HTTP/2.0) is a major revision of the HTTP network protocol used by the World Wide Web. It was derived from the earlier experimental SPDY protocol, originally developed by Google. HTTP/2 was developed by the Hypertext Transfer Protocol working group httpbis (where bis means "second") of the Internet Engineering Task Force. HTTP/2 is the first new version of HTTP since HTTP 1.1, which was standardized in RFC 2068 in 1997. The Working Group presented HTTP/2 to IESG for consideration as a Proposed Standard in December 2014, and IESG approved it to publish as Proposed Standard on February 17, 2015. The HTTP/2 specification was published as RFC 7540 in May 2015.
The standardization effort was supported by Chrome, Opera, Firefox, Internet Explorer 11, Safari, Amazon Silk, and Edge browsers. Most major browsers had added HTTP/2 support by the end of 2015.
According to W3Techs, as of November 2018, 31.8% of the top 10 million websites supported HTTP/2.
In this post, I am going to talk about how to configure FreeSWITCH in a high availability active-passive schema. The active-passive approach will share a floating IP between your VoIP switches and when one gets off-line, the passive one will take control over the IP and it will get the load. For more information about how this works, I strongly suggest you to read my article about the High Availability Cluster Overview; you will understand what you are going to do.
This article will assume the following:
WebP is an image format employing both lossy and lossless compression. It is currently developed by Google, based on technology acquired with the purchase of On2 Technologies.
As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. The webp-related software is released under a BSD license.
For us, as Webmasters, what it makes this interesting is that using the WebP format correctly, you can downsize your image files from 10% to 90%. I will write here how I managed to use this format in an agnostic website. You won't need to mess with your software.
