Configure whether form data and HTTP headers will be sent when entering or exiting Internet Explorer mode

From Microsoft Edge version 96, navigations that switch between Internet Explorer mode and Microsoft Edge include form data.

If you enable this policy, you specify which data types are included in navigations between Microsoft Edge and Internet Explorer mode.

If you disable or don't configure this policy, Microsoft Edge uses the new behavior of including form data in navigations that change modes.

Policy options mapping:

* IncludeNone (0) = Do not send form data or headers

* IncludeFormDataOnly (1) = Send form data only

* IncludeHeadersOnly (2) = Send additional headers only

* IncludeFormDataAndHeaders (3) = Send form data and additional headers

Use the preceding information when configuring this policy.
