That's impossible.  I maintain a LFS Chinese translation and always recheck the
package version after an update.

I had a look on the HTTP response header:

There are no "Expires" or "cache-control" headers so it's possible.  We can add
"Expires: 2019-08-31 00:00:00" for "/lfs/view/stable{,-systemd}/*" to tell the
browser to revalidate the cache for LFS-8.5.  And,
"/lfs/view/{development,systemd}/*" may need "cache-control: no-cache".
