The files are stored in a BLOB field in a database, so that is why the
download comes from a java servlet. I wish I could just FTP.
I have about an 80% download success rate with this format of using a
browser to download the files. However, the script doesn't seem to
always wait for the browser to not be busy before it starts
downloading. When that happens, I get all types of file download
errors.
