Clean redirect after gform_after_submission

Hi! I recently used a variation of gform_after_submission in a custom made plug-in (gform_after_submission_6 to be precise). It does what it should, but I noticed it doesn’t do a “clean redirect”, meaning that if the user refreshes the browser after the form submission, the client asks if said user want to post the data again. This is undesirable behavior, and I noticed that forms in WordPress normally don’t do this.

Now, I could simply add unset($_POST) and do a redirect via a Location header in the gform_after_submission_6 function, but I was wondering if there is a standard Gravity Forms (or WordPress) way to clean the post, and redirect the user safely. Preferably some sort of standard function that is used for this behavior that I can implement, so that the solution is compatible and future proof.

Any help would be appreciated.

I tried this on my local site and after submitting the form I was redirected to the home page of my local site and was able to refresh that page without getting prompted to confirm resubmission.

add_filter( 'gform_after_submission_123', function() {
	wp_redirect( 'https://local.local' );
} );

Curious how that works for you? And how that compares to your actual use case?
