Apache2 configuration for multiple subdomains pointing to different local ports with SSL

README.md

#Apache2 and bind configuration for subdomain for each web application running on different port

• http://gitlab.domain.tld will redirect to https://gitlab.domain.tld to enforce security

• https://gitlab.domain.tld will proxy request to the localhost:3000 where the rails app is running

• http://shellinabox.domain.tld isn't existing and doesn't do nothing. It is a small of security by obfuscation which isn't great, but I prefer people to know to connect through https to go to the shellinabox

• https://shellinabox.domain.tld will proxy request to the localhost:4200 where the shellinaboxd is running
