What’s the difference between a Viewing Session and a Viewing Package?
Viewing sessions require source information for the document that you want to view. There are 3 types of sources to choose from: File, URL, and viewing package.
A viewing package is a file you want to view that is stored in its already “converted state”, which we call “pre-conversion”. This is different than a file or URL because these sources are converted and set in a temporary cache folder for use until the cache is cleared out.
Viewing package information can be set to never expire which is useful if you have documents that will be viewed over and over again by many clients. This allows the server not to have to convert the file every time and increases performance.
