Applying the Apache license, version 2.0 This document is to help Apache developers understand what they need to do to apply the Apache License, Version 2.0 or ALv2 to Apache software, including source code, documentation, and binary distributions. It is descriptive guidance, and does not supplant or otherwise modify any of the terms within the.

Derby release 10.14.2.0 was built using the following environment: Branch - Source code came from the 10.14 branch. Machine - Fedora 27; Ant - Apache Ant(TM) version 1.9.5 compiled on May 31 2015; Compiler - All classes were compiled by the javac from the 1.8.0151 JDK, OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode). The Apache Software Foundation and the Free Software Foundation agree that the Apache License 2.0 is a free software license, compatible with the GNU General Public License (GPL) version 3, meaning that code under GPLv3 and Apache License 2.0 can be combined, as long as the resulting software is licensed under the GPLv3.

HTTP/2 (HTTP/2.0) is the major upgrade over older version HTTP/1.1 protocol.HTTP/1 was released in 1997 and after a long time the HTTP/2 is released in 2015. HTTP/2 protocol is based on SPDY (generally known as speedy). Some of the key improvements of HTTP/2 are:

• Server push: Server will pro-actively sent components to clients, So clients doesn’t need to wait for sending requests to server.
• Multiplexing: Reducing number of active connection by bundling multiple HTTP requests from client and sent to server.
• Encryption: efficiently use to encryption with TLS protocol in HTTP/2 over HTTP/1.1.
• HTTP header compression: Compressed headers will reduce the overhead of additional requests to web server.

This article will help you to enable HTTP/2.0 in Apache web server on CentOS / Red Hat/ Debian and Ubuntu systems.

HTTP/2 protocol supported over Apache version >=2.4.17. So make sure that your Apache version supporting HTTP/2 protocol. If you have not installed Apache or using older version upgrade it first. Use the following commands to add PPA for installing latest Apache2 version on your Ubuntu system.

Verify Apache Version

After successful installation of Apache2 web server on your system, make sure you have Apache >=2.4.17, Earlier version does not supports HTTP/2 protocol.

Enable HTTP/2 in Apache

HTTP/2 protocol requires SSL/TLS virtual hosts. You can’t use HTTP/2 protocol without SSL/TLS enabled websites. Now edit your website VirtualHost and add http2 keyword in listen section.

Verify HTTP/2

Now configure a VirtualHost with SSL for your domain and use following online tool for testing HTTP/2 support on your website.
