Apache 2.4 config to work with 2.2

The access control configuration changed in 2.4, and old configurations aren't compatible without some changes. See here.

If your old config was Allow from all (no IP addresses blocked from accessing the service), then Require all granted is the new functional equivilent.

It appears that there is a difference in how Apache 2.2 handles <Directory> entries that align with DocumentRoot vs. how 2.4 does.

In 2.2, the following code:

DocumentRoot /var/www/myserver
<Directory />
    [...]
</Directory>

would apply any of the directives (such as Options and XBitHack) to the /var/www/myserver directory and files therein.

In 2.4, the configuration needs to change to this:

DocumentRoot /var/www/myserver
<Directory /var/www/myserver>
    [...]
</Directory>

and then apache2ctl restart, and then SSIs will work again.
