This has once been fixed in MGNLDMS-106 but we now have a regression - probably
due to a exception change in recent tomcat versions. Tomcat (using 6.0.26 here)
doesn't throw a SocketException, but a
[ClientAbortException|http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/connector/ClientAbortException.html]
(which is an IOException).
I'd suggest to catch the IOException rather then the SocketException in
DMSDownloadServlet.
