@Adam_G Solved! I don't recall if there is a HISE setting that you also need, but here's the code:
// This file has the redirect to the internet.
var startingPage = FileSystem.getFolder(FileSystem.AudioFiles).getParentDirectory().getChildFile("Images/html/index.html");
web_DOCS_CoreHTML_GUI.set("enableCache", true);
web_DOCS_CoreHTML_GUI.reset();
web_DOCS_CoreHTML_GUI.setIndexFile(startingPage);
In your Images folder, create a folder called "htm" (though you can call it anything), and place your "index.html" (which likewise, can be any file name ending in the html extension). In this file, use this meta-tag.
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<meta http-equiv="refresh" content="0; URL=https://www.ferretsfightingllamas.com" />
</head>
<body>
</body>
</html>
