InetGet does not always force a reload from the remote site

[Akshay07]

Hi all,

I have noticed something which seems to be random, Although I do set the InetGet function to force a reload from the remote site, it is not always doing it. Sometimes, the download stops (and is completed) before the time it should take to complete the full download.

To make sure that this statement is correct, I have used a mobile phone forced in 2G mode as a modem and downloaded a 100MB file. This should take ages to complete. But once in a while, after a few minutes, the download stops, the progress bar (autoit home made) shows "download completed" before the bar is "full" and I can see that I do have the 100MB file saved, with the correct file size.

Once again, it is very random and it is not easy to reproduce.

I am using this:

InetGet("http://www.mywebsite.com/100MBfile, "C:\MyFolder\100MBfile", 1, 1)

Any idea about what is wrong?

My understanding of "Forces a reload from the remote site." is that it should ignore if the file is available in the cache.

Thanks

I had a similar issue when using my iphone as modem, i ignored it and figured it was the NAT settings by the ISP or something.

Thanks.

But I never see this issue if I do the download manually after clearing the cache.

Am I the only having this issue?

Here is the script:

#include <ProgressConstants.au3>
#NoTrayIcon


$sFileToDownload = "abcd.zip"
$sDownloadPath = "http://MyWebSite/" & $sFileToDownload

$totalSize = InetGetSize($sDownloadPath)

$hFileDownloaded = InetGet($sDownloadPath, "C:\MyFolder\" & $sFileToDownload, 1, 1)
ProgressOn("Download progress", "Downloading " & $sFileToDownload, "0 %")

For $i = 0 to $totalSize step 1
    $aDownloadInfo = InetGetInfo( $hFileDownloaded)
    If $aDownloadInfo[2] = True Then ExitLoop
    $percentDownloaded = Round($aDownloadInfo[0]*100/$totalSize, 2)
    ProgressSet( $percentDownloaded, $percentDownloaded & " %")
    sleep(2000)
Next

ProgressSet(100 , "100%", "Download completed.")
sleep(5000)
ProgressOff()

Exit

Might be worth putting in a bug report if you can't find the answer and it still fails to download the file correctly.

What happens when you change this line?

$hFileDownloaded = InetGet($sDownloadPath, "C:\MyFolder\" & $sFileToDownload, 1, 1)

to

$hFileDownloaded = InetGet($sDownloadPath, "C:\MyFolder\" & $sFileToDownload, 9, 1)

Thanks for your answer. As mentioned, this error is not easy to reproduce so I unfortunately cannot just retest this.

But isn't the value 8 (+1) for FTP only? My DL is a HTTP DL.

I don't want to fill a bug report yet, unless I am sure that I am not doing anything wrong.

Not probs. Just a thought, is it possible that a proxy is interfering with it? Might be worth checking to see if HttpSetProxy (1) command has any effect.

No proxy is used.

How do I open a bug report?
