Apache allows you to map file system paths to alias file paths. This allows you to place files or code in a folder outside of your websites install directory, but still allows you to access the contents of the folder through your websites domain name.
Apache is typically configured to include all files in “/etc/httpd/conf.d/” that have the .conf file extension. You can either take a file that is already in this directory or create a new file. e.g. “/etc/httpd/conf.d/custom.conf”.
The following code is used to declare a new alias directory. This directory will not open through the browser as the “Allow from” constraint is only going to allow connections from the defined IP address. Add more addresses to allow more connections or replace with “Allow from all” to let everyone have access.
<Directory "/var/testfolder">
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
#add additional IP addresses.
</Directory>
Alias /test /var/testfolder
