The Documents library supports uploading documents from the user drive to the cache system. This support comes handy when the cache is hosted on a separate machine not accessible to the user. For example, when the Documents class is hosted in a web service with a JavaScript or rich client application. Such as the HTML5/JavaScript version of the LEADTOOLS Document Viewer using the LEADTOOLS Documents Web Service.

There are two ways to upload a document to the cache system. The first, more "automatic" method is to provide the JavaScript File object to UploadFile, which returns a jQuery Promise for a string uri for the cached Document. The second way involves calling BeginUpload to first retrieve the uri, then successive calls to UploadDocument to upload chunks of a JavaScript File object manually. In both ways of uploading, the uri can be used with LoadFromUri to download the Document data.

Refer to UploadFile or UploadDocument for examples.
