# Summary:
# This is a template for Apache virtual host configuration with HTTPS redirection and self-signed certificate.
# 
# Placeholders:
# - {{ server_name }}: Placeholder for the server name.
# - {{ server_alias }}: Placeholder for the server alias.
# - {{ ssl_certificate_file }}: Placeholder for the path to the SSL certificate file.
# - {{ ssl_certificate_key_file }}: Placeholder for the path to the SSL certificate key file.
# 
# Self-signed Certificate Creation:
# Use the following command to create a self-signed certificate and private key:
# sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
# Adjust the paths as needed.
# 
# Permissions:
# After creating the certificate and key files, set the permissions as follows:
# - Set the permissions of the certificate file to 644 (-rw-r--r--).
# - Set the permissions of the private key file to 600 (-rw-------).
# This ensures that the certificate file is readable by everyone and the private key file is only readable by the owner.
# 
# Deployment:
# Replace {{ ssl_certificate_file }} and {{ ssl_certificate_key_file }} in the template with the actual paths to these files,
# and deploy the configuration to your Apache server.
