Via HTTP and providing a URL, not short of downloading the file
and running the checksum over the file locally, and then
downloading the file again and making sure the checksum matches.
Your options for remote checksumming are (1) to have the checksum
on the server as is often the case when you go to download an ISO
and the checksum is an arbitrary link adjacent to the download
link; or (2) have remote-shell access to the machine in question
to run the checksum there instead of locally.
In theory, one *might* be able to use the E-tag mechanism of
HTTP, but there's no guarantee that it's the md5 checksum, an
sha1 checksum, or just some arbitrary identifier. So it would
completely depend on the site from which you were downloading.
