PDFViewCtrlOpenURLAsync Method (String, String, String, HTTPRequestOptions)

Open a PDF file at the given url. This works best with PDF's that are linearized, as pages can be downloaded and viewed in random access order, without the need to download the entire document. A viewing session can also be persisted across multiple viewing/application sessions to remove redundant downloads and improve overall performance by using the optional cache_pdf parameter.
