Date Wed, 29 Feb 2012 10:10:10 GMT

     [ https://issues.apache.org/jira/browse/SYNAPSE-847?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vijayaratha Vijayasingam updated SYNAPSE-847:
---------------------------------------------

    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
