Vamshi Krishna Kaley commented on FLEX-35110:
---------------------------------------------
Not sure if the issue exists in Flex 4, but it is basically using
filereference.upload in a for loop for different files (usually around 120-150
MB) over slow internet connections.
Does Adobe still support Flex 3 bugs , if yes can you share the link where i
can post the support ticket for flex 3 issue.
> Flex based component using FileReference Upload API fails with 400 Bad
> Request for multi upload scenario because of missing boundary conditions

> We have developed a component of multi file upload using flex sdk 3 using
> FileReference Upload built in functionality.
> However we have encountered that the upload fails for more than two files
> over slow transmission networks.
> On further investigation We found that the flash is resulting in I/O Errors
> during the retrieval of total bytes being uploaded for display in the upload
> progress with the log information as displayed below

> =============================================
> Due to this error the POST request is resulting in Bad Requests on the Web
> Server because of the missing boundary closures which are required to
> complete the POST request.
> This issue is always replicable on slow networks which are hovering around

> Request you to look into it and do the needful to provide a fix which needs
