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.

 

Regards,
Terry
