provisional headers are shown

"Provisional headers are shown" is a message that appears in the browser's network tab when making a request. It indicates that the request headers being displayed are not the final headers that will be sent with the request.

This message typically occurs when the browser is waiting for additional information or data before sending the complete request headers. It may happen when a page is loading and making multiple requests, or when the browser is waiting for authentication or other parameters before finalizing the headers.

In most cases, this message is not something that needs to be addressed or fixed by the user, as the browser will automatically handle the finalization of the headers.
