Since 2017-10-15, Magento 2.2 and 2.3 require the `mod_version` Apache module, but do not mention it in their system requirements

Since 2017-10-15, the following commit has added the IfVersion directives to the root .htaccess file:

magento/magento2/blob/82caf48d/.htaccess#L206-L209


      
          <IfVersion < 2.4>
              order allow,deny
              deny from all
          </IfVersion>

The IfVersion directive requires the mod_version Apache module.

This module is not mentioned in the latest Magento 2.2 and Magento 2.3 system requirements:

Magento 2.2

github.com/magento/devdocs/blob/7cbd360b/guides/v2.2/install-gde/system-requirements-tech.md#web-servers

github.com

magento/devdocs/blob/7cbd360b/guides/v2.2/install-gde/system-requirements-tech.md#L29-L29


      
          	In addition, the apache `mod_rewrite` module must be enabled. `mod_rewrite` enables the server to perform URL rewriting. For more information, see <a href="{{page.baseurl}}install-gde/prereq/apache.html">our Apache documentation</a>.

Magento 2.3

github.com

magento/devdocs/blob/7cbd360b/guides/v2.3/install-gde/system-requirements-tech.md

../../v2.2/install-gde/system-requirements-tech.md

If the mod_version module is not enabled, then you will get an error:

Internal Server Error

Migrates Apache Access Syntax to 2.4 on Apache >= 2.4 ### Description …In all .htaccess Files, the Apache 2.2 Auth Blocks like ``` order allow,deny deny from all ``` have been replaced with this block: ``` <IfVersion < 2.4> order allow,deny deny from all </IfVersion> <IfVersion >= 2.4> Require all denied </IfVersion> ``` ### Fixed Issues (if relevant) 1. magento/magento2#10810: Add support of apache2.4 commands in htaccess ### Manual testing scenarios 1. Install on Apache 2.4 and check whether all file access rules work as intended 2. Install on Apache 2.2 and check whether all file access rules work as intended ### Contribution checklist - [x] Pull request has a meaningful description of its purpose - [x] All commits are accompanied by meaningful commit messages - [x] All new or changed code is covered with unit/integration tests (if applicable) - [x] All automated tests passed successfully (all builds on Travis CI are green)
