The Global Config tab on the System Core module is where you set all of the basic settings you want for the system.
Here you set the system name, that gets used in various locations including emails to identify the website. It could be the domain name or the name you call the site.
Set the Cache seconds. Jamroom has a Caching system that allows it to more quickly deliver the content the visitor is looking for. Instead of searching the database for the required information every time a visitor visits the page, it stores that information for a certain amount of time in the cache.
The 'Default Cache Seconds'
sets that period of how long to store the information for before checking with the database again.
The 'allowed domains'
setting allows you to determine if sites other than your own are allowed to use your server to stream media.
All streams and downloads via media players are restricted to the local domain by default - you can enter additional domains (one per line) that you would like to allow access.
