Client behavior when downloading files

I'd imagine that on each collection tick the results of the RequiredFiles webservice call are compared to the file cache object. If any file or layout isn't matching then it would be downloaded.

Hi,

I was wondering what would happen if client-server connection would broke during downloading some files needed to complete layout.

Is it simply skipped, next files are downloaded/or not if next connection problem, and finally xlf is saved od disk and played,

or maybe

files with problems are skipped and saving xlf on disk is skipped also (if at least one file uncompleted), to allow next layout complete try during next collection interval?

As far I remember first option is valid, so there will be any download retry later (in one program run, no after client restart) or broken files would remain on disk until client restart and next collection interval ticks wont help here?

Ie. It's the output of RequiredFiles that drives file collection not the contents of the xlf files.

I'm not sure that i'm understand correctly, so i'm going to ask again to make sure:

So, if some files were broken in effect od connection problems during transfer, there will be redownload as soon as possible (when connection is back again and collection interval tick), right?

That's my understanding, yes. But Dan will be able to confirm.

Alex is correct, the client will re-download any corrupt media when the
collection interval occurs.

If a file fails the download 5 times it will be blacklisted and not
downloaded again.

Can you check in the blacklist table on your server?

If there are records in there that media wont be downloaded, you can delete
those records to clear the block.

Alex, Dan thanks for fast answer :)

It was only a theoretically question, it's hard to check remote client behavior when network connection is broken, so i've decided to ask instead ;)

Thanks again :)
