--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
Even a 404 error may be transient, as a server may just not have gotten around
to indexing new content yet. Other transient errors may persist awhile. I
don't know of any unambiguous winning policy here.
As to the question that, if such a policy were formulated, how could the
results be represented in the filesystem: xattrs, yeah maybe. But even
simpler would be to have the code set the mtime or ctime of the 0-length file
to a cause-related artificial timestamp that will inform the "cache_miss_s"
expiry calculations.
