[Dspace-tech] PDF puzzle
I have a number of publication submissions in some case where there are multiple PDFs in one submission. Normally when accessing PDFs they appear in the browser which is what I want. In once instance there are multiple PDFs in a submission all of which appear in a browser correctly but one of them instead presents an external dialogue requesting what PDF reader should be used. The format for all the PDFs is Adobe PDF The dublin_core.xml There is a similar problem in the forums but no satisfactory answer http://sourceforge.net/p/dspace/mailman/message/31873185/ Extractin strings from the offending PDF and comparing it to a well behaved PDF elicits no obvious differences. Has anyone discovered a reason for this? -- Keir Vaughan-Taylor ERA DSpace Administrator Rm:123 Fisher Library University of Sydney k...@physiol.usyd.du.au ph:+61 2 9351 7408 mb:+61 434 606 885 -- Want excitement?

Is the file that presents the dialogue the largest file of them all, by any chance? You don't say what version of DSpace you're using, but have a look at this configuration option for DSpace 4.2: https://github.com/DSpace/DSpace/blob/master/dspace/config/dspace.cfg#L1447 You might like to read up on the Content-Disposition HTTP header: http://stackoverflow.com/questions/1395151/content-dispositionwhat-are-the-differences-between-inline-and-attachment Essentially, the DSpace setting decides from which size onwards it will send disposition=attachment rather than disposition=inline I believe some browsers / browser plug-ins ignore the content-disposition flag and make their own decision on which one to use. cheers, Andrea -- Dr Andrea Schweer IRR Technical Specialist, ITS Information Systems The University of Waikato, Hamilton, New Zealand -- Want excitement?

Re: [Dspace-tech] PDF puzzle
Hi Keir, i would guess that the file in question exceeds 8MB which is the default inline disposition threshold https://wiki.duraspace.org/display/DSDOC4x/Configuration+Reference#ConfigurationReference-ContentInlineDispositionThreshold if that is the case, you can easilly adjust this value.

Re: [Dspace-tech] PDF puzzle
You were exactly right. Altering the dspace.cfg line to be webui.content_disposition_threshold = -1 xmlui.content_disposition_threshold = -1 resulted in the PDF opening in-line Thank you On Tue, 2014-09-09 at 17:07 +1200, Andrea Schweer wrote: > Hi Keir, > > On 09/09/14 16:53, Keir Vaughan-Taylor wrote: > > In once instance there are multiple PDFs in a submission all of which > > appear in a browser correctly but one of them instead presents an > > external dialogue requesting what PDF reader should be used. > > Is the file that presents the dialogue the largest file of them all, by > any chance?
