Sorry @morganfeeney, I think I misunderstood the original request!
[[redirects]]
from = "/blackpool-hotels-with-parking/blackpool-(beach)"
to = "/blackpool-hotels-with-parking/blackpool-(beach)-:id"
status = 301
query = {id = ":id"}
That will redirect /blackpool-hotels-with-parking/blackpool-(beach)?id=demo to /blackpool-hotels-with-parking/blackpool-(beach)-demo?id=demo.
Head’s up – we automatically pass through the query string parameter from the ‘from’ path to the new (‘to’) path.
If you don’t want ?id=demo in the new (‘to’) path, you can update your rule with a alternate, dummy query string parameter… which actually comes in handy, for knowing if somebody followed the redirect or browsed directly to the new (‘to’) path.
to = "/blackpool-hotels-with-parking/blackpool-(beach)-:id?redir"
