Eh, I'm bitter. Just had a little bit of download left for a 1gb file, and since it stopped, I thought, Oh I'll just double-click it and it will resume... NOPE start all over.

Thanks, Apple. Your stuff has been going downhill for the past 10 years.

Anyone know a surefire way of resuming downloading after a crash/net drop/etc.? In Safari, I mean?

And get off my lawn.

I would never ever download a large file like that in any web browser. Using curl or wget would be much better. This way, you can detach the process using screen, you are free to quit and restart your browser, and you can resume.

You could switch to Firefox and use its download, because the latest version now supports resuming downloads.

Isn't resumable downloads a feature of the server? Safari has supported resumable downloads for as long as I remember, it just depends on whom you're connecting to.

Yes, that's correct. However, I vaguely remember some discussion about Apple's implementation being less lenient with regards to problematic configurations on the server side.

This is truth. Most of the time when Safari can't resume, neither can anything else.

I have never once seen Safari successfully resume a download after a crash, ever.

kylef · Aug 26, 2009, 06:16 AM

Double click the .download file in Finder and it'll resume. I've had the same problem.

CharlesS · Aug 26, 2009, 06:36 AM

That's never worked for me yet.

I can't recall Safari ever resuming a file either.. nor iTunes. Apple isn't all that great in the «resuming download» business it would seem.

OreoCookie · Aug 26, 2009, 07:56 AM

I have used this and it works fine with some servers. In any case, it's not that much an issue if you have a 100 MBit/s pipeline to the internet -- the other side is always slower than you are

The feature to resume is requesting a file from a certain byte, and then simply attaching the rest at the end of the currently downloaded file. That feature is a part of HTTP 1.1, but it is either an optional feature or some servers only implement HTTP 1.0. Safari can certainly do this, but it won't try if the file already downloaded has been corrupted for some reason or other. Same for anything else, really, but maybe Safari's downloading process is slightly less stable and might corrupt files more often.

Atheist · Aug 26, 2009, 08:55 AM

I'm copying this from another of my posts but it's a good explanation of what's going on.

Apple has made their download API (NSURLDownload, which I presume Safari uses) especially strict so that even if the server does support resumes (the HTTP response header includes "Accept-Ranges: bytes") the API will NOT resume if the response header does not include an ETag (helps ensure that when you resume, you are still downloading the original file).

From what I have been able to determine, the requirement for an ETag is not consistently enforced by other software. I have found that some download managers are able to resume files that Safari can't.

It's my experience that a majority of servers don't seem to include this Etag data which is why Safari will not resume many downloads.

I've resumed downloads many times in Safari and iTunes. Actually, I've never seen it fail with iTunes.

besson3c · Aug 26, 2009, 01:25 PM

curl -C - -O "localfile" "http://remotefile"

Um.. lucky you? iTunes doesn't resume download of a dropped podcast. Even on your end.

Safari I have never seen resume anything successfully. But then I'm not just downloading from Apple.com

So does curl resume if you reuse the command?

And thanks for being nice to my b*****ness. Guess you all know me well enough by now.

And what are you all still doing on my lawn?

besson3c · Aug 27, 2009, 12:21 AM

I'm grazing on your lawn, and maybe when you aren't looking I will lay some pipe on it (i.e. porn). What are you going to do about that?

Yes, the -C - argument tells curl to resume and to figure out where to resume from.

dzp111 · Aug 27, 2009, 01:27 AM

FF And Safari -back and forth for me. Tried to dl and print passport docs with FF -no go. Switch to Safari, no problem.

Went to check a "special" site of mine on Safari -no go. Switch to FF? Good to go.

I'm now on FF.

Go figure.

Neither am I, and resume seems to work just fine more times than not.

But then I'm not just downloading from rapidshare.com.

How do you get it not to fill the frame buffer and crash terminal?

besson3c · Aug 29, 2009, 06:41 PM

You add the -O argument plus a file name to output to a file rather than to standard output (i.e. the terminal) like I indicated originally.

Was that an extra dash you had?
