Web Browser Configuration

As Appian provides a Web-based environment for building composite applications, we rely on a default configurations of supported Web browsers for testing. Because it's possible that your organization may enable or disable certain configurations that would impair your ability to use Appian features or access the Appian application, we recommend the following:

  • Use a supported Web browser—see Web Browsers.
  • Configure pop-up blocking plug-ins or features to always allow pop-ups from Appian.
  • Set privacy options to allow you to accept cookies from Appian. Third-party cookies are not used or required by the system.

Additional configuration considerations are described below.

Process Modeler Configurations

The Appian Process Modeler is supported for Edge, Internet Explorer 11, Firefox Chrome, and Safari.

  • With or without the pop-up blocking feature disabled, Google toolbar is not compatible with the Process Modeler.
  • Windows Firewall must be disabled when using the Appian Process Modeler.
  • Additional browser customizations or plug-ins may negatively impact application functionality.
  • Internet Explorer requires that the Allow Programmatic Clipboard Access security option be enabled.
  • Because Debug mode opens in a new window, you will need to disable Block pop-up windows when using Safari. This issue does not affect other web browsers.

To enable the Allow Programmatic Clipboard Access security option

  1. Click Tools > Internet Options.
  2. Click the Security tab, and then click Custom Level.
  3. In the Scripting section, set the Allow Programmatic Clipboard Access option to Enable or Prompt.

Required Configurations

XMLHttpRequest

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 box.

  • Native XML HTTP Support is required by Appian.

XSS Filter

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 box.

  • Appian requires that you NOT disable the XSS Filter.
