/**

* Abstracting this code into a separate file allows us to use it in multiple places
|
|
* without duplicating code.
|
|
* 1. unraidcheck script can call this
|
|
* 2. Unraid webgui web components and request this file
|
|
* 3. Unraid webgui web components can request the json file directly
|
|
* - this is useful for the UPC to check for updates and display a model based on the value
|
|
* - `/plugins/dynamix.plugin.manager/scripts/unraidcheck.php?json=true`
|
|
* - note the json=true query param to receive a json response
|
|
*
|
|
* @param json {string} - if set to true, will return the json response from the external request
|
|
* @param altUrl {URL} - if set, will use this url instead of the default
