Try to disable the "Verify Normalization" on Reverse Proxy Server (ISA 2006): On ISA web publishing rule, right click > config HTTP policy properties > uncheck "Verify Normalization" We're having trouble logging into our reverse proxy address.  If I connect to the internal address it works fine. I get the directories a particular user has permission to get to.  If I use the machines reverse proxy external address and I type the login I just go back to the root and no directories have appeared and it's still got a login link up the top right (ie. it hasn't logged in).  I've checked the web.configs in "rest", "Tokens" and "Services" and changed things like the TokenServiceURL.  I'm not using SSL so my TokenServiceURL is something like:  http://<external address>/ArcGIS/tokens/ I've gone into the rest.config and changed <SoarpUrl>, <SoapSslUrl> and <ServicesDirectoryHelpUrl>.  If I go to the external admin login  http://<external address>/ArcGIS/rest/Admin I get this modification to the url:  http://<external address>/ArcGIS/rest/admin/login?redirect=http%3a%2f%2f<internal address>%2farcgis%2frest%2fadmin note the internal address in the referer. Is that a hint of what is happening? ... View more

Since POSTed requests from the Web API to the proxy always contain text, this content type will work.  However if you wanted to use the proxy to upload a file, you'd probably want to go with multipart/form-data.  I need to use the proxy to upload a file, and to go with multipart/form-data, what can I do? Could you give me some code? ... View more

adam, Yes, you approach produces a high quality PDF for the map. Thanks. Is it possible to create PDF just using current tiled layer, instead of creating a new dynamic layer from the same map service as current tiled layer? We ended up going pretty lean on the exporter. The method we implemented is as follows private void Map2PDF_Click(object sender, RoutedEventArgs e)         {             /* // Don't need the ExportPDF dialog anymore             CMC_Viewer.Views.ExportPDF map2pdf = new CMC_Viewer.Views.ExportPDF();             map2pdf.SetMap(this.Map);             map2pdf.Show();              * */             // Display save-as dialog             SaveFileDialog dialog = new SaveFileDialog();             dialog.Filter = "PDF|*.pdf";             if (!dialog.ShowDialog().Value)             {                 return;             }             // Create a new dynamic layer from the same map service as current tiled layer             ArcGISTiledMapServiceLayer tiled = this.Map.Layers[0] as ArcGISTiledMapServiceLayer;             ArcGISDynamicMapServiceLayer dynamic = new ArcGISDynamicMapServiceLayer()             {                 Url = tiled.Url,                 ImageFormat = ArcGISDynamicMapServiceLayer.RestImageFormat.JPG             };             // When the dynamic layer has initialized create the in-memory PDF document             dynamic.Initialized += (a, b) =>             {                 dynamic.GetUrl(this.Map.Extent,                                (int)this.Map.ActualWidth,                                (int)this.Map.ActualHeight,                                delegate(string url, int width, int height, Envelope extent)                                {                                    // Download a new image of identical to what is currently displayed in the map                                    WebClient webClient = new WebClient();                                    webClient.OpenReadCompleted += (c, f) =>                                    {                                        // Use the dispatcher to force execution in the UI thread                                        Dispatcher.BeginInvoke(delegate()                                        {                                            // Create the PDF document, set document information properties                                            PdfDocument document = new PdfDocument();                                            document.Info.Title = "Map";                                            // Create a new page with the same dimensions as the browser map                                            PdfPage page = new PdfPage(document)                                            {                                                Height = new XUnit(this.Map.ActualHeight, XGraphicsUnit.Presentation),                                                Width = new XUnit(this.Map.ActualWidth, XGraphicsUnit.Presentation)                                            };                                            document.Pages.Add(page);                                            // Create a graphics object for writing to the page                                            XGraphics graphics = XGraphics.FromPdfPage(page);                                            // Add the map image to the page                                            XImage image = XImage.FromStream(f.Result);                                            graphics.DrawImage(image, 0d, 0d);                                            // Save the PDF document to the user specified filename                                            document.Save(dialog.OpenFile());                                            // Notify the user that we're done                                            MessageBox.Show("Map saved to '" + dialog.SafeFileName + "'");                                        });                                    };                                    webClient.OpenReadAsync(new Uri(url));                                });             };             dynamic.Initialize();         } We found that the size of the map to be exported has to be set better than in other examples. Anyway, the code above produces a high quality map. ... View more

I use Silverlight PDF library �??silverPDF�?�, add extension method �??ToStream�?� for  WriteableBitmap and �??ExportPDF�?� for PrintDocument: public static Stream ToStream(this WriteableBitmap writeableBitmap) {             //use EditableImage and  PngEncoder to generate image stream } public static void ExportPDF(this PrintDocument printDocument, UIElement element, Stream outPutStream) {             WriteableBitmap bitMap = new WriteableBitmap(element, null);             Stream stream = bitMap.ToStream();             PdfDocument document = new PdfDocument();             PdfPage page = document.AddPage();             XImage img = XImage.FromStream(stream);             //�?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?��?�.             XGraphics gfx = XGraphics.FromPdfPage(page);            gfx.DrawImage(img, 0, 0, img.PointWidth, img.PointHeight);            document.Save(outPutStream); } Usage: private void btnExportToPDF_Click(object sender, RoutedEventArgs e) {           SaveFileDialog saveFileDialog = new SaveFileDialog();           saveFileDialog.Filter = "PDF file format|*.pdf";           saveFileDialog.DefaultExt = ".pdf";           if (saveFileDialog.ShowDialog() == true)           {               Stream pdfstream = saveFileDialog.OpenFile();               try               {                      PrintDocument printDocument = new PrintDocument();                      printDocument.ExportPDF(theUIElementYouWantToPrint, pdfstream);                      MessageBox.Show(string.Format("PDF is exported and saved in: {0}", saveFileDialog.SafeFileName));               }               catch (Exception ex)               {                     MessageBox.Show(string.Format("Error creating PDF document: {0}", ex.Message));               }           }       } It works. The problem is that the image loses quality, especially for the text in theUIElementYouWantToPrint. I find that lost the quality in using EditableImage and PngEncoder (or JpgEncoder) to generate image stream: 1. UIElement -> WriteableBitmap (quality not lost) 2. WriteableBitmap -> PNG or JPG Stream (quality lost) 3. PNG or JPG Stream -> PDF (quality not lost) Any ideal? ... View more
