Determines how the JavaScript support library file is loaded.
Supported values are:
WebResource The default is WebResource which means a call is made back to the Web Connection Server to retrieve the resource. The script is cached so it loads once per user in most cases. Because the file is loaded internally there's no external file required.
EmbeddedInPage You can embed the script into the page which is useful for debugging, but not recommended for runtime operation since the script essentially loads into every page that uses this control.
ExternalFile Lets you use an external file reference to the wwWebAjax.js file. The file is installed in the Images directory of a new Web application.External files will cache, so they normally load only once.
