In the Form Redirect scenario, the Siebel Web client submits a request to the Siebel Server. The Siebel Server creates a form with the necessary authentication information in it, and then sends the form back to the browser. The browser loads the form and then submits it to the external host for processing. The external host sends back the results, which the browser displays in a new window.
The Form Redirect disposition option is usually displayed in a new window, rather than inline with other Siebel applets.
The Form Redirect disposition type is not commonly used with Siebel business applications.
