Page_Load Event Fires Twice When Sending Down a PDF

J

Jay Douglas

Hello all,
I have a asp.net page that creates a pdf on the fly and sends the pdf
down to the browser. When calling the page up in IE the Page_Load event is
fried twice. This doesn't happen with mozilla, just IE. This is a big
problem because the PDF can be 20+ MB in size and is causing some serious
performance issues. Writing the PDF to the filesystem then a redirect is
not an option. I was wondering if anybody has any input on how to correct
the issue or when MS is going to be able to fix this bug. The
Autoeventwireup is set to false. (I've also trited using Reponse.End() and
Response.Flush() )

Here is the code for the Page_Load event:

int docId;
ErezDoc doc;
byte[] b;

if (Request.Params["d"] != null)
{
if((docId = Convert.ToInt32(Request.Params["d"])) > 0)
{

doc = new ErezDoc(docId);

b = doc.GetData();

Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", b.Length.ToString());
Response.AddHeader("content-disposition", "inline; filename=" +
doc.DocId.ToString() + ".PDF");
Response.BinaryWrite(b);

doc.Clear();
}
}

Hi Jay,

I've got a couple of questions for you:
What version of the Framework are you using? Also, is this page set as the
default page in IIS? Third, is smartnavigavtion set to true for this page?

This combination of settings has been known to cause the page_load event to
fire twice in certain circumstances on v1.1

Thanks,
Chris [MSFT]

Chris,
This is not the default page in IIS. I'm using the v1.1 framework. I
am having these issues on IIS v5.1 (XP) and v5.0.

I am encountering the exact same problem. It also occurs with Word
Documents.

I have created a simple web page that experiences the same behavior with the
following code.....

{
System.IO.FileStream FileContent;

string FileName = "Adobe1";

byte[] array;
FileContent =
System.IO.File.Open("C:\\AA_NET_Examples\\AlchemyWebFramesTest\\" + FileName
+ ".pdf", System.IO.FileMode.Open, System.IO.FileAccess.Read);
page.Response.Clear();
page.Response.ContentType = "application/pdf";
page.Response.AddHeader("content-disposition", "inline; filename =
Adobe1.pdf");
page.Response.AddHeader("content-length",
FileContent.Length.ToString());
array = new byte[FileContent.Length];
FileContent.Read(array, 0, (int)FileContent.Length);
page.Response.BinaryWrite(array);
FileContent.Close();

page.Response.End();
}



Thanks in Advance

It is like that, but the fix for that problem is to check the
useragent.
But in my case, the useragent is exactly the same for all requests.
