But, you will see a significant reduction
in your bandwidth cost, if you start using this Bitrate
Throttling Module. It would be configured for any video/audio file types,
and in fact for any MIME types such as .PDF, .DOC, etc.
I would explain here how to configure
throttling setting specifically for PDF files.
In the IIS Manager, select your web site,
and select "Bit Rate Throttling" under Media Services. First of all, make sure
that the bandwidth throttling is enabled in the site.
Now, Right click on the pane and select
"Add Throttle Setting..." or select the same from the "Actions Pane". Type
"application/pdf" as the MIME type, and enter "Fast Start" and "Throttle rate"
