"GET /.hash=" in HTTPd logs?

I've noticed recently on a few different machines entries like this:

GET /.hash=8148dd8cd5c884d62cab26ccfa1aeaa045eab116

GET /.hash=6baa50082310ba631358f57c8fb7eaadf752e055

Any idea what is going on here?

Is this some 0day exploit? Something old that is going round again?

Certainly nothing I have experienced before.

Thanks
