AlertWire

AlertWire is a system for centralized administration of alert/messaging for multiple sites.
Once your site has been configured in the AlertWire system, you can add this plug-in and set the data-token to enabled the checking of alerts. When the 
page is rendered, a <code><script></code> tag will be inserted into the document being rendered.
How AlertWire Works
<ol>
<li>The page is generated with the correct API server and <code>data-token</code> configured, typically added to the bottom of the page <code>body</code> tag.</li>
<li>An async script tag is executed (late as possible) which loads a small (<4K) javascript plug-in. This plug-in has no dependancies and will 
not interfere with any existing frameworks like jQuery</li>
<li>A cross-domain JSON request is made to the AlertWire API service to determine if there are any active alerts for the <code>data-token</code> specified.</li>
<li>If there are one or more alerts to view, a CSS style-sheet will also be loaded from the API server.</li>
<li>The alerts are then generated dynamically into the document and styled automatically. There are several formats that are rendered 
differently (e.g. page-top, lightbox, etc.).</li>
<li>Tracking pixels are generated to record when a check-in for alerts cccurs and when a view or close or click-through of an alert occurs.</li>
</ol>
Notes
<ul>
<li>The javascript plug-in and CSS style-sheet are publically cached from a CDN and are very small, the impact on load times should be tiny.</li>
<li>The CSS file is only loaded if there are alerts to be rendered.</li>
<li>The javascript plug-in only introduces one symbol into the global scope, the AlertWire module. All other functionality is behind that scope.</li>
<li>The plug-in will set a cookie when a user closes an alert to ensure it isn’t displayed again. Depending on the alert type, this cookie may be a 
session cookie or a durable cookie with a 1 year expiration.</li>
<li>A very small font file will be downloaded for the alert icons the first time an alert is displayed to an end user.</li>
</ul>
