Hello, I've looked through the archives and I see that this issue has been raised before (http://dev.list.galaxyproject.org/file-download-returns-empty-file-or-webpag...) but without a noted resolution. I am running Apache as proxy but I downloads from multiple machines and browsers are either empty or return an error after clicking the download button. I enabled Apache xsend file: <Location "/"> XSendFile on XSendFileAllowAbove on XSendFilePath /galaxy </Location> And configured galaxy to be aware of this in universe_wsgi.ini apache_xsendfile = True. I have checked the apache error logs and do not see any issues reported. Any help would be appreciated. I've ended up changing apache_xsendfile = false just so that i can download data. How do I get galaxy apache and xsendfile to work properly? Cheers, Ian
