Web Control Disposition Type
For the high interactivity client only, you can use the Web Control disposition type when the IFrame or Inline disposition types do not work. Typically, this is because of hardcoded references to specific frame names in the external application's HTML. For more information, see Portal Agent Restrictions.
The Web Control disposition type embeds an Internet Explorer ActiveX object in the Siebel page and provides it to the external application. In the Web Control disposition type, similar to the IFrame type, the external application sends content directly to the user's browser, bypassing the Siebel Server. The external application then behaves as if the ActiveX IE instance is an independent Web browser.
NOTE: The Web Control disposition type is not available in Siebel Open UI.
