Thanks to you both!
4WD, that may very well be the exact Flash-drive Website setup in the Newest Version. The write-up sounds exactly like it! As best as I can remember it was on some site like Geeks-R-Us or ?? It was 5 years ago i think but this one looks perfect for the task.
And Shades' program suggestions may also be right on the Mark. The thing was, back then, I was only dabbling in HTML web-code with no added confusion of PHP and MySQL. I and a helper have found several way to setup a PDF viewer using straight HTML but when we try to use the native PHP routines which handle the requests for the documents, it seems to fall off the tracks somewhere.
Flex Paper looked like a good and affordable solution to the problem but contacting their Support Department has been a challenge so far. If it were not for Chrome being the Party Spoiler, IE11 already handles the PDF's in a viewer and so does Edge. But Chrome is probably 20% of the Browser market so I can't ignore that. Besides, using a well-written Hosted Viewer would allow me to add all the "page-flips" and other toys.
As for KARMA and HTTP MONITOR, (EVEN the DOM in IE11) you may well be right that it was something built into the developer tools such as a Tech Net Package. I should check there. Thanks for the tips.
