Protecting and Hiding your Bing Maps Key

Introduction

When using Bing Maps for Enterprise in your solution/application, you need a Basic Key (limited free trial) or an Enterprise key to use the services. For example, you would add a Bing Maps Key to the script URL loading the Bing Maps Web Control like this:

<script src="https://www.bing.com/api/maps/mapcontrol?callback=GetMap&key={your bing maps key}"></script>

Now your key is open text on your site source code and people who look can find and use your key. Search engines will index your page and, as a result, will also store your key. Is this a problem? Not really.
