Many FTP servers support resuming incomplete downloads, as do some HTTP servers. I don't know if Rev supports resuming transfers, though. I kind of doubt it. Not a bad feature request, or it could be done with an external...

Maybe a wrapper around libcurl (http://curl.netmirror.org/libcurl)?

My Rev program needs to upload and download a file of roughly 2 MB in size 3-8 times every 30 minutes via a wireless connection. This wireless connection is through the built-in airport card in an IBook. Sometimes this connection is received via a wired DSL or cable modem (and wireless router), but sometimes it feeds off a Powerbook connected to the net via a Verizon 3G PCMCIA card (using Apple's Internet Sharing capabilities).

Using the 3G card is obviously less stable than a direct wired connection, especially in more rural areas. Sometimes the Internet connection just drops off during the middle of the upload or download. I'd like suggestions for the most stable way of transferring these files, and secondly, what I can do if the file transfer is interrupted part way through.

For example, does it matter if I use:

- get URL
- libURLDownloadToFile
- read from socket
- load

Are any more reliable for dealing with 2 MB files via a slower connection or just in general?

Secondly, if a file is partly transferred, is there any way to restart the transfer from where it left off?

Thanks.
