At present, in WW 2.15 and apparently back to WW 2.11, the setting
$server_apache_version = '2.4';
in site.conf should work, but not forms like
$server_apache_version = '2.4.29';
with 3 numeric parts to the version number. This is due to a bug in the code adding support for this setting. Hopefully this will be fixed in WW 2.16, and maybe in a hotfix to WW 2.15.
