Run Headlamp with a base-url

Normally Headlamp runs at the root of the domain. Hower you can also ask to run it at a base-url like “/headlamp” for example.

• default at the root of the domain: https://headlamp.example.com/.
• base-url https://example.com/headlamp/

A warning about multiple apps on the same sub domain

Hosting multiple websites (apps) on the same origin can lead to possible conflicts between the apps. Each app is able to access information and make requests of the other. Therefore each app needs to be tested together, trusted, and a compatible Content-Security-Policy should be considered for each of them.

If in doubt, host Headlamp on a separate origin (domain or port, don’t use the -base-url option).
