copied!<p>I've been trying to get this aspx page to serve up a pdf. It works correctly in Firefox, but IE gives </p> <blockquote> <p>Internet Explorer cannot download getform.aspx from SERVER_NAME<br> Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found.</p> </blockquote> <p>This is the general functionality of my code. It's spread across multiple functions (this is why we're not using WriteFile - sometimes we generate the pdf on the fly), but this is generally it:</p> <pre><code>FileStream fs = File.Open(Path.Combine(PdfBasePath, "form.pdf"), FileMode.Open, FileAccess.Read); Stream output = Response.OutputStream; byte[] buffer = new byte[BUFFER_SIZE]; int read_count = fs.Read(buffer, 0, BUFFER_SIZE); while (read_count > 0) { output.Write(buffer, 0, read_count); read_count = fs.Read(buffer, 0, BUFFER_SIZE); } fs.Close(); Response.Clear(); Response.ContentType = System.Net.Mime.MediaTypeNames.Application.Pdf; Response.AddHeader("Content-Disposition", "attachment; filename=form.pdf"); Response.Output.Flush(); Response.End(); </code></pre> <p>Looking at Fiddler, the page is being fetched using this:</p> <blockquote> <p>GET /getform.aspx?Failure=Y&r=someencryptedstring HTTP/1.1</p> </blockquote> <p>It is being returned to the browser thus:</p> <blockquote> <p>HTTP/1.1 200 OK<br> Date: Thu, 09 Apr 2009 22:08:33 GMT<br> Server: Microsoft-IIS/6.0<br> X-Powered-By: ASP.NET<br> X-AspNet-Version: 2.0.50727<br> Pragma: no-cache<br> Content-Disposition: attachment; filename=form.pdf<br> Cache-Control: no-cache, no-store<br> Pragma: no-cache<br> Expires: -1<br> Content-Type: application/pdf<br> Content-Length: 628548</p> </blockquote> <p>This is really bugging me. I'm not using SSL, otherwise <a href="http://support.microsoft.com/default.aspx?scid=KB;EN-US;q316431&" rel="nofollow noreferrer">this KB article</a> would seem to apply. Anyone have any ideas?</p>
