Singula - All hostnames collapse into one port.

A simple application that serves multiple hostnames over HTTPS using self-signed certificates.

Setup Steps

1. Add Local Domains

   Add the following entries to your /etc/hosts file:

   127.0.0.1 domain1.localhost domain2.localhost
   

2. Generate SSL Certificates

   Run the certificate generation script:

   chmod +x generate_certs.sh
   ./generate_certs.sh

   This will create self-signed certificates in priv/certs/ for:

   • domain1.localhost
   • domain2.localhost

Running

1. Start the App

   rebar3 shell

   The cowboy will start with:

   • HTTP on port 8080 (redirects to HTTPS)
   • HTTPS on port 8443

Testing

Visit the following URLs in your browser:

• http://domain1.localhost:8080
• http://domain2.localhost:8080
• https://domain1.localhost:8443
• https://domain2.localhost:8443

Note: Since we're using self-signed certificates, your browser will show a security warning. You can:

• Click "Advanced" and proceed anyway (temporary)
• Add the certificates to your system's trusted certificates (permanent)
