> When try to pull larger file from an ftp location , i face the following issue[1]..I
used following proxy configuration[2]
> The  issue is here,  vfs transport listener closes the stream before the vfs transport
sender reads it.. As a workaround, i added a Stringbuffer @ listener with a limited buffer
size to read the soap envelope..
> Attached the patch with this workaround..
> Please review and commit
