I have a client who is struggling with the slow download of pdf files on the Internet. My client has very large PDF files that are almost 10 MB. It takes 3-4 minutes to download. Files will not be displayed until the entire file is downloaded. We and they saw other sites where PDF files load one page at a time, so the end user can start viewing the file as the rest of the page is still loading in the background. Gives the illusion that the page loaded faster.
According to the documentation they see, IIS 6 should automatically do this if the PDF file is created using "Optimized for quick browsing on the Internet." It is checked, and the file still does not load the page at a time.
They searched and found nothing, except that IIS will do this automatically if the file is saved correctly.
How can they sink the pdf? Is it because the PDF was saved in a special way? Is this a java script that handles loading? Or are there any changes that need to happen in IIS?
thank
Update: The file starts as follows:
%PDF-1.4
%âãÏÓ
171 0 obj << 0/Linearized 1
Linearized?
PDF does not feed from aspx / asp page. (It is simply posted directly on the site and associated with it).
