             Summary: Flex based component using FileReference Upload API fails with 400 Bad Request for multi upload scenario because of missing boundary conditions
                 Key: FLEX-35110
                 URL: https://issues.apache.org/jira/browse/FLEX-35110
             Project: Apache Flex
          Issue Type: Bug
          Components: RPC: General
            Reporter: Vamshi Krishna Kaley


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
==============================================
388956 AVMINF: MTHD flash.events::ProgressEvent/get bytesLoaded ()
388958 AVMINF: MTHD flash.events::ProgressEvent/get bytesTotal ()
388960 AVMINF: MTHD flash.events::IOErrorEvent ()
388962 AVMINF: MTHD flash.events::ErrorEvent ()
388964 AVMINF: MTHD flash.events::TextEvent ()
388965 AVMINF: MTHD flash.events::Event ()
388967 AVMINF: MTHD flash.events::Event/ctor ()
388970 AVMINF: MTHD FileUpload/OnIOError ()
388972 AVMINF: MTHD flash.events::IOErrorEvent/toString ()
IOError Event : Dispatched when the upload or download fails.[IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2038: File I/O Error. URL: <<http based Post URL>>
=============================================

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 100Kbps

Request you to look into it and do the needful to provide a fix which needs to be incorporated as one of our customers are critically affected with this functionality miss.
