Security Settings Setup

Tested for IE, CHROME, FIREFOX browsers:

//Call following function to get correct WebDAV url for your document
//provide cms document url, onSuccess and onFailure handler functions as argumnts
//you can pass an empty domain parameter value. In that case AppBase will calculate solution domain automatically
var u = Ecx.getWebDAVAccessToken(YOUR_CMS_URL, '', davSuccess, davFailure);
 
//onSuccess handler example. it will parse obj.WebDavUrl url and open it in ms word application
function davSuccess(args) {
    var obj = Ext.decode(args.responseText);
    var webDAVURL = obj.WebDavUrl;
