InetGetInfo - $INET_DOWNLOADEXTENDED

[mLipok]

I'm using InetGet + InetGetInfo  to download quite big file 137 MBytes.

On one PC I get from  InetGetInfo      @error = 32 and @extended = 12002

What could be causing this problem ?
Do you know the AutoIt some methods of downloading with resuming ?

Are you able to dowload it manually? How long does it take to return that error?

I don't know internal behaviour of InetGet, but the only way to download huge files avoiding errors using WinInet API is to split the file request in multiple InternetReadFile calls, each one returns few bytes.

Resuming download is possible, but it is based on server support of Range and If-Range HTTP request headers.

Read here and here, and this is a partial Autoit implementation using WinHTTP.

I have this problem only on one host, but it works correctly on 40 another host.
So this is not problem with FileSize but with InternetConnection.

Thanks for links. I will look at this.

What I meant is that you can't know how InetGet behaves, for example in this case we need to download little chuncks of the file with a longer timeout.

Have you tried to download that file with a customizable download manager? If it fails too, I don't know if you can make a script that successfully download the file...

In the meantime I have tried Mozilla "Download Them All" with no success

 

[j0kky]

I just read about InternetSetFilePointer, a native WinInet function which accomplish download resuming, you can try to make something like this one (finally the autor uses anyway Range header, but it's because it would write code for multiple downloads), remembering to set an appropriate timeout through InternetSetOption.

I see that I should try _WinINet_InternetReadFile()

It might be a problem on the server side since @mLipok is not able to download the file manually.

[mLipok]

This server is my own server, and I said that I'm able to download on many other host.

 

[TheDcoder]

Oops, looks like I misunderstood... have you tried downloading with different browsers?

[mLipok]

There is really something wrong with InternetConnection on this host. As DownloadThemAll not working properly.

I will try to find other solutions.
