Invalidate cache for /cog/tile endpoint

[lawrencenika]

I was loading a url object at /cog/tile?url=gs://abc/file.tif, it works. But when I deleted gs://abc/file.tif and created a new gs://abc/file.tif with the different content, my titiler is still showing the old tile content? Is there a way to invalidate cache by an API call manually?

I m using GCS bucket without versioning.
