Redirects back to the last page

Uses the Referer header to do a redirect to page that got you here.

In case the Referer header is not set this function will redirect to /. Use redirectBackWithFallback when you want to specify a custom fallback path.

Example:

action LikeAction { postId } = do
    post <- fetch postId
    post
        |> incrementField #likesCount
        |> updateRecord

    redirectBack

Redirects back to the last page or the given fallback path in case the Referer header is missing

If you don't care about the missing-Referer-header case, use redirectBack.

Example:

action LikeAction { postId } = do
    post <- fetch postId
    post
        |> incrementField #likesCount
        |> updateRecord

    redirectBackWithFallback (pathTo ShowPostAction { postId = post.id })
