Hi fas,

Looks like my problem is harder to solve than it seems.  I've created a jira
entry for a proposed enhancement in fileupload that could help me solve this
bug I'm working on.  Here's the link if you are interested:
https://issues.apache.org/jira/browse/FILEUPLOAD-168

Thanks for the help!

Best Regards,
Paul Rivera
