5.0 manual (pdf) is not readable by Acrobat plugin in IE: is it just me?

["Vijay Aswadhati" <wyseman@...>]

If you click on http://www.lua.org/ftp/refman-5.0.pdf, the Acrobat plugin
complains that the file is corrupted. The same link when saved to a file is
readable by Acrobat. Is this an Acrobat problem or due to incorrect
mime/headers sent by the server?
