WCF / ASMX :: Content Type Text / Html Of The Response Message Does Not Match The Content Type Of The Binding

May 7, 2010

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.

C# - How To Compress .ashx Content

Jun 2, 2010

In my web application I use an ashx file to write a file to the browser. I've noticed that there's no compression over the .ashx file, but only over my .aspx files.

Is it possible to compress .ashx? And if it is possible, how?

Currently I use global.asax to handle the compression:

<%@ Application Language="C#" %>
<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.IO.Compression" %>
<script runat="server">
void Application_PreRequestHandlerExecute(object sender, EventArgs e)
HttpApplication app = sender as HttpApplication;.......

As you can see only files which inherit from 'Page' are compressed, and my ashx file is not of type Page. So I added a condition and now it works just fine:

if (!(app.Context.CurrentHandler is Page ||
app.Context.CurrentHandler.GetType().Name == "SyncSessionlessHandler" ||
app.Context.CurrentHandler is ViewMht // This is the type I had to add
) ||
app.Request["HTTP_X_MICROSOFTAJAX"] != null)

Setting Content - Type Of Empty Response In MVC

Dec 27, 2010

In 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];
while ((cb = legacyInput.Read(rgb, 0, rgb.Length)) > 0)
clientOutput.Write(rgb, 0, cb);

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.

How To Set A Default Content-type Of Text / HTML In Web.config

May 4, 2010

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.

Content Type When Serving A File In A Generic Handler?

Dec 10, 2010

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:


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?

Why Does IIS7 Ignore Content-type Header When Use Stream Files

Feb 9, 2010

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:

JQuery :: Uploadify Not Finding Handler?

I am using the jquery Uploadify plugin to upload multiple files. It works great on my development machine; however, when I run the code on the server I get an error that the upload.ashx generic handler (that Uploadify calls to save the file) is not found. Wondering what would prevent it from being found in the server environment. I have even put a copy of the file in every directory to no avail.

Javascript - Uploadify Response Value Is Always Undefined?

Mar 4, 2011

I'm using Uploadify to upload some images with ASP.NET. I use Response.WriteFile() in ASP.NET to return the result of the upload back to JavaScript. As specified in the documentation I'm using onAllComplete event to check for response string from ASP.NET.

The problem is it that the alert(response); is always undefined in JavaScript.

JavaScript code as below:

$(document).ready(function() {
var auth = "<% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %>";


Reason for the FormsAuthenticationTicket object is to pass the authentication cookie though when using the Uploadify with Firefox.

I have seen many examples where Response.Write returns a value back to the onAllComplete event. But all I get is undefined. I have also tried to use Context.Response.Write, this.Response.Write, HttpContext.Current.Response.Write. They all return undefined.
