I had not heard of this before (sorry for not researching better).

I found the spec:
And the support in Apache:

Do you know of any website that implements this?  Or if the major user agents
(Firefox/IE/Chrome) support it?

This places a burden on the server because it has to compute the checksum upon
every request.  It would be much better to compute it once, and serve it many

To my knowledge, I don't know of any websites that implement this for large
file downloads.  Implementing this change would make it easier for developers
and publishers to ensure files are downloaded correctly.

I will try to check and research more on its implementation.
