After updating from Acrobat Reader 9 to 10 we have noticed that PDFs viewed in the browser are left behind in the Temp-folder even after the browser has been closed.
Http-headers in the response from the server
Content-Disposition: inline; filename="xxxxxxxx.pdf"
Browsers: Firefox 3.6, Opera 11, Safari 5
Plugin: Acrobat Reader 10
Simply add a .pdf extension to the file and open again in Acrobat Reader. Since the server has set headers indicating that this PDF should not be stored locally, it is a severe security hole leaving traces of this PDF on the filesystem.
Is this a problem Adobe is aware of? When can we expect this to be fixed?
PDF files must be stored locally in order to be viewed by the Reader plug-in. This has always been the case.
Thank you for you quick response!
In Acrobat 9, I cannot find the PDFs in the Temp-folder after the browser has been closed.
In Acrobat 10, PDFs are left behind in the Temp-folder even after browser close.
To me, this looks like a bug in Acrobat 10. Would you not agree?
