* **HTTPS**: Always serve the app over TLS, especially when session cookies contain sensitive identifiers. However, <Icon icon="https://mintcdn.com/dangowebsolutions/h7v7ncdoSDUTq6Mf/icons/commtrackr/commtrackr.svg?fit=max&auto=format&n=h7v7ncdoSDUTq6Mf&q=85&s=aa307feda8f84b0e50116ef911d268f9" className="islight" width="88" height="68" data-path="icons/commtrackr/commtrackr.svg" /><Icon icon="https://mintcdn.com/dangowebsolutions/h7v7ncdoSDUTq6Mf/icons/commtrackr/commtrackr-dark.svg?fit=max&auto=format&n=h7v7ncdoSDUTq6Mf&q=85&s=bc035891dcb55bf41b0e7d9267d343cb" className="isdark" width="88" height="68" data-path="icons/commtrackr/commtrackr-dark.svg" /> **CommTrackr** can operate over HTTP in trusted internal networks or development environments.
* **Session Store**: Use a production‑grade store such as <Icon icon="https://mintcdn.com/dangowebsolutions/h7v7ncdoSDUTq6Mf/icons/directadmin/databases.svg?fit=max&auto=format&n=h7v7ncdoSDUTq6Mf&q=85&s=801944cee045f7e7ec21ce888cebcfc6" width="50" height="50" data-path="icons/directadmin/databases.svg" /> **MySQL** rather than the default memory store.
* **Environment Variables**: Keep secrets (`session.secret`, DB credentials) out of source control.
* **Scaling**: Because <Icon icon="https://mintcdn.com/dangowebsolutions/h7v7ncdoSDUTq6Mf/icons/commtrackr/commtrackr.svg?fit=max&auto=format&n=h7v7ncdoSDUTq6Mf&q=85&s=aa307feda8f84b0e50116ef911d268f9" className="islight" width="88" height="68" data-path="icons/commtrackr/commtrackr.svg" /><Icon icon="https://mintcdn.com/dangowebsolutions/h7v7ncdoSDUTq6Mf/icons/commtrackr/commtrackr-dark.svg?fit=max&auto=format&n=h7v7ncdoSDUTq6Mf&q=85&s=bc035891dcb55bf41b0e7d9267d343cb" className="isdark" width="88" height="68" data-path="icons/commtrackr/commtrackr-dark.svg" /> **CommTrackr** stores data in the session, ensure your session store is shared across all server instances (e.g., a central <Icon icon="https://mintcdn.com/dangowebsolutions/h7v7ncdoSDUTq6Mf/icons/directadmin/databases.svg?fit=max&auto=format&n=h7v7ncdoSDUTq6Mf&q=85&s=801944cee045f7e7ec21ce888cebcfc6" width="50" height="50" data-path="icons/directadmin/databases.svg" /> **MySQL** cluster).
