Web Browser to Unreal Engine - Messaging System

With the help of the Messaging System of Custom Web Browser (by using the HandleOnBeforeBrowse method), we are able to send a message from web browser through a specified URL scheme.

Custom Web Browser by default is inspecting any URL starting with uewebbrowser:// scheme. When this kind of URL received, it sends a message to Unreal Engine instead of loading it in the web browser.

For example, suppose you wrote a Javascript code which loads a uewebbrowser:// URL:

window.location.href = "uewebbrowser://purchase?name=" + myPurchase.name + "&price=" + myPurchase.price;

In Custom Web Browser, an OnMessageReceived event will be raised when this URL is loaded.
