I got this error
Response object error 'ASP 0156 : 80004005'
Header Error
/ordermgmt/updateorderstatus.asp, line 1390
The HTTP headers are already written to the client browser. Any HTTP header modifications must be made before writing page content.
I put Response.Buffer=true;
Stilll it is showing error.
I have put reponse,Redirect # this line number and that will be executed a number of times (it is in a loop).,After the first iteration it is showing this error
Yes buddies, Its Fixed.Before Response.Buffer ,i included another file.Now i changed it to below the Response.Buffer=True line .Its working now .Thanks
Check that you're not outputting anything at all - even a blank line before your start ASP tag will cause this problem.
The first Response.Redirect changes the headers (and probably forces a Flush, because with a redirect, there can be no content).
The second Response.Redirect changes the headers again (probably to the same thing, but that doesn't matter, as the header were written during the Flush())
You have to enable buffering on specific page, then you can remove this error like:
<% Response.Buffer = True %>
on top of the ASP form
The same applies if you are using Response.Flush()
Set the property storage enabled = true in IIS > ASP > Storage enabled

I am at a loss here. I am trying to transmit a file on the local intranet site. When I get a download prompt in IE11, it says:
Do you want to open or save "SomePage.aspx?fileID=12345"? [open] [save] [cancel]
Instead of..
Do you want to open or save "Document.pdf"? [open] [save] [cancel]
It works perfectly fine on Chrome. The file gets downloaded with the correct filename. But for some reason, IE isn't setting the name and instead uses the ASPX name.
The code is rather straightforward:
testFile = New System.IO.FileInfo("\\someshare\somefolder$\Document.pdf")
Response.Clear()
Response.AddHeader("Content-Disposition", "attachment; filename=" & testFile.Name)
Response.AddHeader("Content-Length", testFile.Length.ToString())
Response.ContentType = "application/octet-stream"
Response.TransmitFile(testFile.FullName)
I've tried a number of different header options and the MIME type makes no difference.
Does anyone have a clue why this would be happening?
Notes: Not HTTPS. It is not limited to PDF, same happens with .TIF, .DOC, and every other format I've tested.
EDIT: Have also tried Response.WriteFile as well as Response.BinaryWrite .. same thing each time.
EDIT2: Simplified everything down to a single button on a completely blank page.
You should have quote marks around the file name. See 19.5.1 on http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html
i.e.
Content-Disposition: attachment; filename="fname.ext"
so...
Response.AddHeader("Content-Disposition", String.Format("attachment; filename=""{0}""", testFile.Name))
Unfortunately I have not been able to test if this solves your issue as I don't have access to IE11 at the moment.
So I know this question is older, but the solution I finally came up with to this problem is to add the following two lines to my code.
Response.SuppressContent = True
and
HttpContext.Current.ApplicationInstance.CompleteRequest()
You have said in previous comments that you have tried the CompleteRequest command to no avail.
As a note, I am not 100% certain to the logistics of the Response.SuppressContent() command.
The documentation says that it indicates "whether to send HTTP content to the client". This seems counter intuitive to the process of sending the request body back to the client, however, it appears to only suppress the parts of the response that include any HTML.
It seems that the partial or incomplete HTML is what causes the filename to appear as the page name regardless of the headers set and sent. Stripping this out should cause the file to download properly.
Interestingly, this solution is actually born out of a secondary issue where once I was able to export the file using ClosedXML, i was receiving messages when opening the document that there were errors than excel would try to fix.
Response.SuppressContent actually fixed that as well. Hope this helps or at least points you in the right direction.
Im getting following error in a asp file.Below is my error.I dont get the error offen but I do get it sometimes.
Error:-->
"Response object error 'ASP 0156 : 80004005' Header Error /UseFull/Quelables.asp, line 3 The HTTP headers are already written to the client browser. Any HTTP header modifications must be made before writing page content."
//code in that asp page
<!--#include file="folder1/newFill.asp" -->
<%
Response.CharSet ="UTF-8"
Dim asp, strQue
Line 3 here is "Response.CharSet".What is the problem?
please suggest some answer.
Sent headers cannot modify. Looks like buffering is on and headers already sent to the client. To get rid of this, you need to turn on buffering. When buffering is off, all operations over Response object made immediately and it's irreversible in most cases. There must be Response.Buffer = False in folder1/newFill.asp. Change it to Response.Buffer = True.
By specifying the Response.Charset you are actually instructing asp to set an encoding metatag and yes this is set in the header of the page and must be set before anything is output to the page (e.g. any response.write).
If you need your output to be in UTF-8, try putting the charset on top of your page as follows:
The output is what you are setting with the meta tag and could also be set as follows:
<% Response.CharSet ="UTF-8" %>
<!--#include file="folder1/newFill.asp" -->
<%

i am sending a large amount of excel content data to the browser using Page.Response.Write("") in a for loop.
before starting the loop i am changing the conetnt type of the reponse.context property to "ms-excel".
if i have an exception during that for loop , i try to popup an error message to the browser by registering an HTML startup script block and Write it to the browser. before the write i change back the content type to be text/html.
but i get an error that say that is not possible to change the content type after sending the HTTP Headers.
How to notify the browser about an error that occured during that for loop?
Is it possible to have more that one respone to the same browser tab?
by the way,right now i don't want to use ASP.NET AJAX.
Did you try Response.ClearHeaders(); before changing the context type?
If that doesn't work because your Response.Write is causing problems, you might think about going the route of building a string before deciding your content type and then setting the headers.
Loop trough the content and add to a StringBuilder
If no error, set contenttype to ms-excel and write out SB
If there is an error, leave contenttype as it is write out your error message as needed.
Page.Response.Write("") will send data to the browser. When you do that the browser needs to know the type of content it gets in order to render it correct. If you already told the browser what kind of content you have(and even if you don't, you are already sening data with Response.Write, it will use the default value which I think is text/html) then you can't take it back. Whatever you are saying to the client is said and you can't take it back.
The way to solve your problem is to cache the reply as suggested by Doozer.

My web application uses chunked encoding. I'd like to have the behavior where if any chunk generates an error, I can properly set the error code and redirect to an error page using that. Right now it seems like that can only happen if the error occurs during the first chunk because the response headers must be sent in the first chunk. Is there any way to make this work or get the behavior that I want? Thanks.
The HTTP spec allows you to provide additional headers as a "trailer" after your last chunk, which should be treated just like headers at the top of the response:
https://www.rfc-editor.org/rfc/rfc2616#section-3.6.1
Here's an example:
http://www.jmarshall.com/easy/http/#http1.1c2
I have a very interesting issue with only specific IE implementations. I have an ASPX page that is used to write files down to the user, as part of the process the page uses the following code to write the file to the user.
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=download" + System.IO.Path.GetExtension(oInfo.SupportingFilePath));
Response.ContentType = "application/octet-stream";
Response.WriteFile(Server.MapPath(oInfo.SupportingFilePath));
Response.End();
In 99.5% of the cases this works just fine, however, in certain rare circumstances within IE only on specific machines, the user is prompted to download the .aspx page, and/or is given an error message.
Anyone have an idea of what is going on here?
Per RFC2231, MIME headers' parameter values have to be included in double quotes: http://www.ietf.org/rfc/rfc2231.txt (page 3, if you are interested).
It should be something like "attachment;filename=""download" + System.IO.Path.GetExtension(oInfo.SupportingFilePath) + """");
Although this should not be happening because you've set the ContentType and content-disposition, I believe that IE's built-in MIME sniffing/handling is what is causing the problem here. Here are a couple of work-around/hacks you can try:
Add the file extension to the query string on the .aspx page that is transferring the file, i.e., http://blahblahblah/page.aspx?.ext
If you are using IE 8, you can specify another response header for "nosniff," as specified here.
I'm still having issues with this, as documented here, but I hope one of these helps.
