- * @class Roo.data.HttpProxy
- * @extends Roo.data.DataProxy
- * An implementation of {@link Roo.data.DataProxy} that reads a data object from an {@link Roo.data.Connection} object
- * configured to reference a certain URL.<br><br>
- * <p>
- * <em>Note that this class cannot be used to retrieve data from a domain other than the domain
- * from which the running page was served.<br><br>
- * <p>
- * For cross-domain access to remote data, use an {@link Roo.data.ScriptTagProxy}.</em><br><br>
- * <p>
- * Be aware that to enable the browser to parse an XML document, the server must set
- * the Content-Type header in the HTTP response to "text/xml".
- * @constructor
- * @param {Object} conn Connection config options to add to each request (e.g. {url: 'foo.php'} or
- * an {@link Roo.data.Connection} object. If a Connection config is passed, the singleton {@link Roo.Ajax} object
- * will be used to make the request.
