RemarksThis exception is thrown when a RAD PDF DocumentKey (or DocumentKey for Lite Documents) is not found in the RAD PDF SQL database (or PdfLiteSessionProvider for Lite Documents).
While a large number of RadPdfDocumentKeyNotFoundExceptions being thrown might indicate an attempt to guess a Document Key (which is theoretically impossible) or otherwise hijack a session, this exception occurs inevitably in most RAD PDF setups. In most cases, this exception can be logged as a warning. For example, when a browser session being "re-awoken" (e.g. a laptop screen is opened), this may cause the cached page to fetch RAD PDF's IFRAME, causing it to look for a document key which may have expired long ago.
