is_apache in vars.php does not always work

[amandato]

The $is_apache variable does not always work when using an Apache module like security2_module with the SecServerSignature option. By removing the word "Apache" from the name of the server vars.php will no longer detect that the server is Apache.

A simple solution is to add an addition check:

function_exists('apache_get_version')!== false

Any Apache only function will work.

See attached patch from WP 4.4.2

I discovered this caused issues with the RewriteRules, randomly WordPress would add index.php/ within the permalinks when editing the permalink options in the wp-admin.

Not sure if this should be called a bug or an enhancement, leave it up to core team to decide that.

I would not remove the first 2 checks though, it is possible that the apache_get_version is disabled in the php.ini. I would recommend adding the option to the current checks just to be 100% sure.

Did I place this ticket in the right component?

Hello,
what happened to the patch? do you need another patch format? The bug still exists in the latest version...

Well, alternative solution:

in wp-config.php

<?php
$_SERVER["SERVER_SOFTWARE"] = "Apache";
