[Savonet-users] custom protocol

[Tony Miller]

Hi,

I'd like to create a custom protocol that is exactly the same as the
http,https protocols, but leaves the files in /tmp and reuses them
(caching) if they are already downloaded. Is this possible? I know caching
is not a simple issue.

I was looking through scripts/protocols.liq, but I couldn't quite figure
out what exactly controls the somewhat random looking output filenames
(/tmp/liq02469a.mp3, etc).

It looks like there is a file.exists function as well, so seems like this
could be possible. I'm sure there are lots of edge cases though, as is per
the course with any sort of caching.

Thanks!

Hi Tony,

The most simple way, I believe, would be to alter the download protocol
code to first download the file in a caching directory of your choosing and
then copying it to the destination requested by the protocol handler.

Does that make sense?
