DocumentUltimate v3.1.0 is released

This release includes the following changes:

• Added: Brought back DocumentSource for convenient loading of documents from a stream or byte array (also via callbacks that return these). New DocumentViewer.DocumentSource property can be used as an alternative to DocumentViewer.Document property.

  //Load document from a stream:
  
  documentViewer.DocumentSource = new DocumentSource(
      new DocumentInfo(uniqueId, fileName), 
      new StreamResult(stream)
  );

  //Load document from a byte array:
  
  documentViewer.DocumentSource = new DocumentSource(
      new DocumentInfo(uniqueId, fileName),
      byteArray
  );

   

• Added: Load balancer support. DocumentViewer can now work properly in multi-server environments or cloud (e.g. Azure) where in-memory session is not available. Session serialization is fixed to support all session modules. You still need to have a shared cache folder between multiple instances/servers.

• Changed: Usage of DocumentCache class. Path will be passed in the constructor to prevent user forgetting setting it. Easier way to get a DocumentCache instance when inside in the same web application which uses DocumentViewer.

  /*
  Pre-caching in other applications.
  Usually you would only need to pass path parameter unless you change default values of other parameters:*/
  
  
  DocumentUltimateConfiguration.Current.LicenseKey = "QQJDJLJP34...";
  
  var documentCache = new DocumentCache(@"C:\some\cache\folder");
  
  documentCache.PreCacheDocument(
    new DocumentOptions
    {
      Document = @"C:\some\document.pdf"
    }
  );

  /*
  Pre-caching in the same web application which uses DocumentViewer. 
  This DocumentCache instance is already filled with necessary information like cache path, license key etc.:*/
  
  
  var documentCache = DocumentUltimateWebConfiguration.Current.GetCache();
  
  documentCache.PreCacheDocument(
    new DocumentOptions
    {
      Document = @"C:\some\document.pdf"
    }
  );

   

• Improved: DocumentCache locking, prevented double entries for same uniqueId with different file name if requested at the same time.
