This web browser API is used by modern web applications (such as Google Maps) to enable XML-based requests and responses from a web server/application server. It sends and receives XML and plain text data that is used to update the current web page without the need to load a new web page on the client. Internet Explorer allows you (or your system administrator) to disable the "Enable Native XML HTTP Support" setting on the Advanced tab of your Internet Options dialog.
Internet Explorer has a feature called the "XSS Filter" that detects reflected cross-site scripting (XSS) vulnerabilities. Users can configure this feature on the Advanced tab of the Internet Options dialog.
Appian requires that you NOT disable the XSS Filter.
