Hello:

 

A customer reported the following error.

 

Flash: The upload task is interrupted! io Error #2038

Server side error: System.Exception: Error:Failed on

ReadEntityBody, unexpected data ending (2)

261544932/580366736

 at CuteWebUI.a.a(HttpContext A_0,

HttpWorkerRequest A_1, MemoryStream A_2, FileStream

A_3, String& A_4)

 at CuteWebUI.a.b(HttpWorkerRequest A_0)

 at CuteWebUI.UploadModule.d(HttpContext A_0)

 

Any ideas about the cause of this and the solution?

Hi,

 

When uploader throws this error, it means the server did not get any data from client side for 12 seconds.

 

Maybe the customer will also see the progress have stopped for 12 seconds before the alert be shown.

 

Network problem can cause this issue.

 

If your customer can always get such problem,

 

You can test this appSettings in web.confg:

 

<add key="CuteWebUI..AjaxUploader.UseAspNetStream" value="True" />

Interesting.

What exactly will this setting do?

Thanks for getting back .

Another thing, my boss just asks me the following:

 

Is it possible, when the connection is lost, that the uploader will retry a few times, preserving the bytes already uploaded, so when the connection is reestablished, the upload will continue at the same point, similar to how FTP works.

 

Is there a similar mechanism available within ajaxuploader?

Hi,

 

The newest version which was released yestoday now support this feature.

 

Please download it and try again.

 

 

For silverlight it will try to resume the uploading automatically.

 

For Flash mode , you need set the FlashLoadMode to true , but this is not good for large files.

 

 

So, for big files, I suggest you use UploadType=Silverlight

That sounds very interesting.

 

Two questions: Why exactly is FlashLoadMode set to true bad for large files?

 

And second, is there a  timeout value that we can customize, of how long an interruption can maximum be, for ajaxuploader still be able to resubmit the data?

 

Thank you.

Hi,

 

Silverlight can read small chunk of data from the file

 

But Flash only support read all file data into memory.

 

So if use Flash mode to open a 500MB file , 500MB data will read to memory , and the browser will hang for a while.

 

Now we do not provide timeout setting . the auto logic is ,

 

If the file is transfered for 10 minutes , the uploader will try to resume at lease 5 minutes.

 

User can cancel the current file if he see the progress is stopped and do not want to wait.

I see.

 

We installed the latest version and tested both silverlight and flash. As you predicted, flash was terrible with large files and the setting flashloadmode set to true.

Silverlight seemed to do a bit better,but still had big delays, and wasn't able to finish, showing the following error in an alert window:

 

 

Any idea what this error is about?
