The acrobat plugin is definitely unhappy with these sorted ranges that Zope uses for creating the response. Acrobat expects the ranges in the very same order it has requested them.
Sorry, further reading on my part. What Acrobat reader version, Browser version and Zope version? *Not* sorting the ranges causes considerable performance loss on the Zope server. I have tested Acrobat reader version 5 on Mozilla (0.9 and up), Netscape 4.7 and Internet Explorer 5.5 and up with this and all combinations work with the current code. There was a bug in the way ranges that touch upon each other (no overlap, just no seam) were optimized away, and the way Netscape 4.7 uses a draft version of the spec instead of the released version. These have been fixed. As the spec does not prohibit sorting, and perfomance loss is fenomenal on large files, I would need considerable justification for not using sorted ranges. If you use Zope 2.4, then you are probably experiencing one of the above mentioned bugs. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------
