Hi guys, I have setup a test galaxy and configured Apache as proxy. It's been running fine when I did all testing on my machine with Chrome. Recently, I let some of my colleagues to try it out, then they experience some file download issues. On one machine, both FireFox and IE8 downloaded empty files (zero byte). But on another Linux machine, FireFox downloaded a complete file successfully. On two MacBook machines, Chrome encountered webpage error (only the right hand side) as soon as download button was pressed. Saying: *This webpage is not available* * * *error 100 (net::ERR_CONNECTION_CLOSED): The server unexpectedly closed the connection.* I have seems someone posted the exact same issue before but no solution has been given. I enabled Apache xsend file: <Location "/"> XSendFile on XSendFileAllowAbove on</Location> And configured galaxy to be aware of this in universe_wsgi.ini apache_xsendfile = True. Any help will be appreciated. Thanks Derrick
