So, you would have to change it by setting crud.settings.delete_next = URL(...).
The redirect really isn't necessary, though, and the only way to avoid it would be to specify a crud.settings.delete_onaccept callback and raise an HTTP() exception to immediately return a 200 response. crud.delete() is also somewhat inefficient, as it first retrieves the record from the database before deleting it (not sure why). Ultimately, you're probably better off with db(...).delete() rather than using Crud. In fact, Crud is generally not recommended anymore, as most of its functionality has been subsumed by SQLFORM.process() and SQLFORM.grid().
