4.1 – config.html
After opening the /config.html page, you have the possibility to configure all the important settings in SparkView.
Quick overview of the individual topics:
If you access the page from the localhost, no password is required to start the configuration. Outside the localhost, the management password must be entered.
Below you will find a descriptive overview of the different settings areas (tabs here):
