ALLOWED_HOSTS setting in Django specifies a list of host/domain names that the application can serve. It is a security measure to prevent HTTP Host header attacks, which can exploit vulnerabilities in web applications.In full-stack development, the
ALLOWED_HOSTS setting is essential for production deployments. For example, if the application is hosted on example.com, the setting should include ['example.com'] to ensure that only requests from this domain are accepted.By using
ALLOWED_HOSTS, developers can protect their applications from unauthorized access and improve security.
