Description

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
