Files not uploading in Safari on Apple computers

Reply Quote

Our Apple users are complaining that files don't get uploaded. When using any browser on a Windows computer, everything is working just fine.

This week I bought an Apple MacBook Air laptop to be able to test things like this myself, and I can confirm... files don't get uploaded when working with Safari.

I downloaded and installed the latest Ajax Uploader DLL just now, to make sure I'm not using an older Ajax Uploader version, and the issue is still the same.

Most of the time the upload seems to happen: I can select one or more files to upload, and the progress bar gets filled up. But the files never arrive in the specified location on the server. And I've searched other locations on the server as well, but the files don't seem to arrive at all.

Sometimes I get the following Javascript alert:

"AjaxUploader global error: Flash : The upload task is interrupted io Error #2038"

Like I said, the problem is specific for Apple computers.

Is this a know issue? What can I do to fix this?

Regards, Marja

I've found that Error #2038 is related to the size of files to upload. We have a limit of 10 Mb and when trying to upload files larger than that, this error occurs on Apple computers.

The strange thing is that on Windows computers we get a regular alert explaining about the file size, and on Apple computers we get this weird technical error message. Why is that?

Anyway, the original main problem persists:
When using Safari on an Apple computer, the files don't get uploaded. Not even when they are way smaller than 10 Mb.

This is specific to Safari. When using Firefox on Apple, everything is fine.

What causes this weird Safari issue?

Correction the #2038 is not directly related to file size. At least not in Safari.

I'm on my Apple computer now, in Safari, and when trying to upload a file of eg. 6 Mb, I get the following error (JavaScript alert):

AjaxUploader file error: About Downloads.lpdf , Flash : The upload task is interrupted! io Error #2038
Server side error :

And below that is the html of the page my users get redirected to by the error handler in our application when an exception occurs.

For your information, the exact same error occurs in Safari when uploading a file in your demo page at http://ajaxuploader.com/Demo/multiple-files-upload.aspx.

Hi MarjaR,

Is your site online? If so, can you send me the uploader page url and show me the full steps to reproduce this issue? I will check it and get back to you as soon as possible.

Is your site using window authentication?

Is your site on the load balancing, web farm, cloud environment?

Can you reproduce this issue with the example below on your end?

<%@ Page Language="C#" %>

<%@ Register TagPrefix="CuteWebUI" Namespace="CuteWebUI" Assembly="CuteWebUI.AjaxUploader" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>example</title>

</head>

<body>

<CuteWebUI:UploadAttachments ID="uploader1" runat="server" UploadType="iframe">

</CuteWebUI:UploadAttachments>

</form>

</body>

</html>

Regards,

Ken

Our application is running in many shared hosting environments on regular Windows servers. So no load balancing, no web farm, no cloud environment or whatsoever.

But as I said in a previous post: the #2038 issue is reproducable in the Ajax Uploader demo page at http://ajaxuploader.com/Demo/multiple-files-upload.aspx.
Just try uploading a file of eg. 6 Mb using Safari on Mac.

So I don't think you need me to upload a test page somewhere?

The button for the CuteWebUI:UploadAttachments uploader does nothing at all?

Some more information:

The #2038 only happens with some file types, not all.
I'm new on the Apple laptop and I don't have any files there yet. So I tried to upload a file named "About Downloads.lpdf" that is present on the laptop by default.
Safari nor Firefox like that... they both present the #2038 error. When uploading eg. an image, the #2038 issue does not happen.
As it turns out, when uploading eg. an image with Safari, there is actually a "persisted.<GUID><filename>.resx" file placed in the upload-directory. But the file does not get moved to a given non-temp directory afterwards.
When working in any other browser, uploaded files get moved (and possibly resized), but not in Safari. And that why the upload didn't seem to happen at all.

The code in my real upload page is:

<CuteWebUI:Uploader ID="Uploader1" AutoUseSystemTempFolder="false" TempDirectory="~/sysfiles/TempAjaxUploader/"
MultipleFilesUpload="true" OnFileUploaded="AjaxUploader_FileUploaded" InsertButtonID="btnBrowse"
ManualStartUpload="true" runat="server">
</CuteWebUI:Uploader>

Why isn't the OnFileUploaded event triggered when working with Safari?

Hi MarjaR,

You page http://webwarenet.clubwebware03.nl/uploadtest.aspx works fine for me. I tested on safari 5.1 (windows).

What Mac/safari version you are testing?

Did you install the flash plug-in for your safari browser?

Please try the url below, does it get the same issue?

Safari 5.1.1 on Mac OSX 10.7.2

Safari on Windows does not have this issue. All is well there.
