I'm getting this message when going to a web app that accesses my service.
"The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8)..."
The thing is, it happens once in a while even when no changes have been made to the service or the web app. And I can make it go away most of the time by going directly to the .svc?wsdl page in my browser and then coming back to the web app.
I'm using the following piece of code:

I connect to a web address using HttpWebRequest object (http://www.website.com/page1.aspx), this page should redirect me to another page (http://www.website.com/page2.aspx). What I want to do are two things:

My response should be a url.I'l getting respStr="http%3A%2F%2..."How can I convert respStr to string in order to create URI url = new URI(respStr); ?
When inserting a binary file do you know what will be the correct content type for extensions like .txt or .gif or others not in your sample? Is there a list of correct content types?

I have a file, a.pdf, stored on a SharePoint server behind Windows authentication. I want to make a.pdf available through another Web app with forms authentication. Basically, link is clicked and up pops the open / save as dialog for the pdf (or other document file) I've set up my HTTPWebRequest and passed credentials, getting my data into a stream (file.GetResponseStream).
I've tried converting the stream to a byte array and then using response.write or response.output.write with no luck (stream not seekable) I've tried using a streamreader and doing a response.write(streamreader.readtoend()) and response.write(memorystream.toarray(),0,memorystream.toarray().length) with no luck (the message received from the server could not be parsed).
i have managed to get the only table from rediff and its working fine the whole table is showing.
1 .But when i try to see the string by responce.write it show only 1st line not the full table..Why??
2. I want to feed this in my data base so the full table can be stored nad retrived..How?

My problem is that although the response length is correct at around 21MB, the stream is returned far too quickly (pretty much instant) and the byte array ends up being filled with only a small number of bytes. The response is clearly not returning the full file so what am I doing wrong?
I am uploading a file on a MVC Action. The file I am uplading is a PDF document.However, on the controller I get "application/octet-stream" as ContentType instead of "application/pdf".Do I need to install Adobe Acrobat Reader on the system so that a PDF file is recongnized?

View 1 RepliesIn order to support a legacy application that's in the field, I need my ASP.NET MVC app to return an empty response that also has a Content-Type. One of IIS, ASP.NET, or ASP.NET MVC is removing my Content-Type when I send back a null response. Is there any way around this? (While not requiring an empty response with a set Content-Type would obviously be the ideal solution, the clients are already out there, and many of them cannot be upgraded.)
EDIT: Since there was a request for code: I'm proxying the request from the new web application to the one that older clients rely on. To do this, I have a subclass of ActionResult, called LegacyResult, that you can simply return for those methods that need to be handled by the old software. This is the relevant part of its code:
public override void ExecuteResult(ControllerContext context)
{
using (var legacyResponse = GetLegacyResponse(context))
{
var clientResponse = context.HttpContext.Response;
clientResponse.Buffer = false;
clientResponse.ContentType = legacyResponse.ContentType; /* Yes, I checked that legacyResponse.ContentType is never string.IsNullOrEmpty */
if (legacyResponse.ContentLength >= 0) clientResponse.AddHeader("Content-Length", legacyResponse.ContentLength.ToString());
var legacyInput = legacyResponse.GetResponseStream();
using (var clientOutput = clientResponse.OutputStream)
{
var rgb = new byte[32768];
cb;
while ((cb = legacyInput.Read(rgb, 0, rgb.Length)) > 0)
{
clientOutput.Write(rgb, 0, cb);
}
clientOutput.Flush();
}
}
}
If legacyInput has data, then Content-Type is set appropriately. Otherwise, it's not. I can actually kluge the old backend to send an empty v. non-empty response for exactly the same request, and observe the difference in Fiddler.
EDIT 2: Poking around with Reflector reveals that, if headers have not been written at the time that HttpResponse.Flush is called, then Flush writes out the headers itself. The problem is that it only writes out a tiny subset of the headers. One of the missing ones is Content-Type. So it seems that, if I can force headers out to the stream, I can avoid this problem.
I have a simple upload page using the html file element. I choose a .pdf file to upload and when I inspect the Content type of the file when it goes to server the value is "application/msword" instead of "application/pdf"
View 1 RepliesI am working in asp.net MVC & on the view has to show both json & xml content depending on some condition.
I have to change the content type of the page at runtime ie,
if the condition for json is fulfilled then set page contenttype = "text/json"
&
if the condition for xml is fulfilled then set page contenttype = "text/xml".
I have tried setting default content type on view as
<%
@
Page
Language="C#"
Inherits="System.Web.Mvc.ViewPage"
ContentType="text/json"%>
& in controller class if xml condition is fulfilled then chnage it like :
this.Response.Clear;
this.Response.ContentType = "text/xml";
BUT it didn't work for me .
I'd like to set the default content-type for web pages in my ASP.NET MVC application to text/html.
I know this can be done by adding a ContentType="text/html" to all of my <%Page%> elements, but I'd prefer to use the web.config instead. How can I do that?
Edit: I know that "text/HTML" is the ASP.NET default, but for unknown reasons Opera still tries to parse my web site as XHML unless I explicitly set the content-type in my <%Page%> element.
I'm busy writing a handler to serve various documents for download or presentation in web forms pages. The documents range from various image formats, to PDF, to MS Office documents, to generic binaries. My basic draft of the download process is as below:
[code]....
However, I have some misgivings about lumping all documents together as application/octet-stream, and I would prefer, if feasible, to use a more specific content type per document type. I have a DB table for document types where I could store this. Am I going in the right direction, and if so, where can I find a suitable starting list of content types for document types?
I tried to post data to client HTTPPost URL, as per the client specification I need to post the data using "Post" method and I used the same. But it throws an error "The remote server returned an error: (500)Internal Server Error". in the HTTpWebResponse.My post URL does not have any specific page like http://abc.com/post/post.aspx. the actual URL looks like "http://abc.com/post", Can we post the lead without any specific page like I said in the above URl?

I have a simple web site with two pages. One displays a list of files, and the other streams a file when it's clicked in the list. All was fine in production for 6 months, but now I have to move the site to Windows 2008/IIS7. I have it mostly working, but the files don't open properly (in Firefox) because my content-type header is being ignored. On the production site (IIS6) the headers are (using Fiddler):
HTTP/1.1 200 OK
Date: Tue, 09 Feb 2010 16:00:51 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Content-Length: 236841
Cache-Control: no-cache, no-store
Pragma: no-cache
Expires: -1
Content-Type: application/octet-stream
but on the test IIS7 server I get:
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 236841
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Fiddler also reports a protocol violation and says "Content-length mismatch: Response Header claimed 236841 bytes, but server sent 238378 bytes."
My code looks like this:

String destinationFolder = destinationPath + "/" + vendor;

Does a HttpWebResponse.StatusCode detect Asp.Net errors? Mainly a yellow screen of death? Some Background: I am working on a simple c# console app that will test servers and services to make sure they are still functioning properly. I assumed since the HttpStatusCodes are enumerated with OK, Moved, InteralServerError, etc... that I could simply do the following.
WebRequest request = WebRequest.Create(url);
request.Timeout = 10000;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response == null || response.StatusCode != HttpStatusCode.OK)
{
// SERVER IS OK
return false;
}
else
{
// SERVER HAS SOME PROBLEMS
return true;
}
I found out this morning however that this doesn't work. An ASP.Net application crashed showing a Yellow Screen Of Death and my application didn't seem to mind because the response.StatusCode equaled HttpStatusCode.OK. What am I missing?
HttpWebResponse response;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException webexp)
{
response = (HttpWebResponse)webexp.Response;
}
I would like to call multiple times to a web resource, however I get forbidden when asking the webresponse.

I'm using an AsyncFileUploader and I want to check if the uploaded file is of valid type (e.g. jpg, gif, png, etc...) and if not the AsyncFileUploader should be colored in Red (like ErrorbackColor setting to Red)
Is this possible either using Javascript or FileUploader events?
