That’s what I was trying to do (using Apache 16)
I have two enabled config files.

<VirtualHost *:80>
    ServerAdmin admin@something.com
    ServerName mydomain.com/project_1
    ServerAlias www.mydomain.com/project_1
    DocumentRoot /var/www/project1/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

And the other one (for an entirely different project) would be:

<VirtualHost *:80>
    ServerAdmin admin@something.com
    ServerName mydomain.com/project_2
    ServerAlias www.mydomain.com/project_2
    DocumentRoot /var/www/project2/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

I’ve tried it and it didn’t really work.

Do I need to change my domain droplet records to make it work? Because there’s no option for routes there..

I assume I did something stupid and that this question is very unprofessional, but still, I would love to get some help please :)
