Prevent overwriting local file when server download is unavailable

[tomimatko]

We have some syndicated shows that RadioBOSS downloads from a server.
The problem occurs when there is no new file available on the server. In that case, we expect RadioBOSS to simply keep and play the existing file stored locally on the computer.
However, when there is nothing available on the server, RadioBOSS still downloads some small file/data of only a few KB and overwrites the valid local audio file.
It would be useful if RadioBOSS could detect that there is no valid file available on the server and, in that case, not download or overwrite anything. The existing local file should remain untouched and be used for playback.

It looks like the server returns an error page (e.g., 404 Not Found) and RadioBOSS does save this page.

It downloads whatever the server returns, and as far as I know, it will overwrite the target file in (almost) any case when the download command is called - not only on successful download.

From your description, you want it to function like Podcasts feature, when it always simply plays/downloads the latest file available. Maybe the source of those shows can supply it in podcast XML?
