Does Abyss support byte-serving of PDF files? Byte-serving permits large, multi-page PDF documents to download very quickly by enabling each page to come down, in sequence, as fast as it can and display to the user. In other words, the user doesn't have to wait on the whole document to download before it is available for on-line viewing.
IE and other browsers have plug-ins that permit them to display a PDF file within the browser window. We use PDF documents extensively for security reasons and many may be printed in hard copy for field use (one-time use). PDF formats make the printing format nearly perfect compared to HTML or text.
Byte serving is technically defined as "linearization", i.e., the process of preparing a document for "byte-serving". Byte-serving permits individual pages to be downloaded by performing byte range requests to the web server. The benefit is best illustrated when an extremely large PDF document is downloaded. Instead of waiting for the entire document to stream down to the browser, byte-serving allows for the first page (or any desired page) to load almost instantaneously. For byte-serving to work, both the web browser and the web server must support HTTP 1.1 Byte Range requests. Most modern browsers (e.g. IE 4.x and higher and Netscape 4.x and higher) and servers (e.g. IIS 4.x and higher) support this functionality. There are PERL scripts available on the Internet for those web servers that do not support byte range requests.
If the answer is no, it would be a great future enhancement.

It is called "Partial downloads support" in http://www.aprelium.com/abyssws/. You have nothing to configure to make it run, the server is smart enough to use it with clients (browsers, download managers, acrobat reader) that claim they support range requests.

Hooho, I KNEW I did not really know what that really meant when I first saw that description. I assumed was download mean just plainly that. Humm.... I guess all web server does this... atleast the one I went to show this type of behavior. I always thought it was the setting in the browser or somewhere of Windows.
