public interface ICustomUI
This is the interface for a custom user interface plug-in. It can be used to create custom pages that runs
in-process within the product.
It also enables custom third-party integration when there is a need to initiate it via HTTP.
This plug-in will be invoked when there is a request with a URL that matches the following pattern:
/sst/admin/extui//*
For example:
/sst/admin/extui/mycustomfolder/index.html?view=all
Warning: The plug-in implementation must be re-entrant. In other words, multiple threads might call the same
plug-in instance at the same time.
