Preserve Session after Server Restart

By default, the session secret key is generated dynamically when the backend server starts. This applies to both PD embedded mode and standalone mode. This results in invalidating your previously acquired session token. For easier development, you can supply a fixed session secret key by setting the DASHBOARD_SESSION_SECRET environment variable:

DASHBOARD_SESSION_SECRET=aaaaaaaaaabbbbbbbbbbccccccccccdd

You can also specify it via .env file.

The supplied secret key must be 32 bytes, otherwise it will not be effective.

Note: the maximum lifetime of a token is 24 hours by default, so you still need to acquire token every 24 hours.
