Suggestions on mechanism or existing code - maintain persistence of file download history

[jkn]

Err, well, thanks for that discussion gents...

As it happens I do know how to use a database, but I regard it as overkill for
what I am trying to do here. I think a combination of hashing the URL,
and using a suffix to indicate the result of previous downloaded attempts, will
work adequately for my needs.

    Thanks again
