Currently, I have a VirtualHost defined like so:

<VirtualHost *:80>
    ServerName mydomain.com
    ServerAlias otherdomain.com
    DocumentRoot /var/www/project/
</VirtualHost>

How can I make an Alias that only affects the otherdomain.com domain:

Alias /sub /var/www/other

So that:

http://otherdomain.com/sub -> /var/www/other
http://mydomain.com/sub -> /var/www/project/sub

The VirtualHost in question is not that simple in reality, so I'd rather not make separate VirtualHosts just for this. Are there any conditional expressions or similar that I can use inside the VirtualHost? Something along the lines of:

<VirtualHost *:80>
    ...
    <If ServerName=otherdomain.com>
        Alias /sub /var/www/other
    </If>
</VirtualHost>

No you cannot use an alias in a If. 

If "%{HTTP_HOST}

is not compatible with Alias, using it will result with Apache not starting and outputting the error message:

Alias not allowed here

You should create another VirtualHost with the corresponding name and configured with your alias.

Here are the relevant bits of the Apache documentation:

http://httpd.apache.org/docs/trunk/mod/core.html#if

and

http://httpd.apache.org/docs/trunk/expr.html

In that case, something like this should work:

<If "%{HTTP_HOST} == 'example.com'">
    Alias /sub /var/www/other
</If>

I believe you will need Apache 2.2 or greater for the "If" functionality.

I think i've found a way around.

<Directory /var/www/other>
  Require all denied
  <If "%{HTTP_HOST} == 'example.com'>
    Require all granted
  </If>
</Directory>
Alias /sub /var/www/other

<If> + Require in .htaccess file inside /var/www/other should work too.
