They don't need it to be impossible - just difficult. As the documents are 200 pages long they don't think anyone would screengrab them - and if they did they would be in violation of an NDA. They just want to make it highly unlikely that the document would end up being emailed around. We have successfully used HTTP headers to prevent the files from going to the cache. Now we just need to implement some kind of crude encryption/decryption of the swf. We're not trying to guard against pro-developers or hackers - just against tech-savvy business people who might look in their temporary internet files, or do a "view source" to find the file, etc. On Fri, Jun 27, 2008 at 8:14 PM, Paul Andrews <[EMAIL PROTECTED]> wrote: > ----- Original Message ----- From: "Stuart Campbell" < > [EMAIL PROTECTED]> > To: <[email protected]> > Sent: Thursday, June 26, 2008 1:22 PM > Subject: [Flashcoders] Document viewer > > > Hi, >> >> I have a project where I need the client to be able to view documents in >> the >> browser (PDF, Word, RTF and Excel).
