C# - Exactly Does Response.Redirect("~/...") Put In The HTTP Response?
Nov 24, 2010
I've just finished reading URL vs. URI vs. URN, in More Concise Terms, and it's really helped understand the distinction between the three terms. Since then I've skimmed the RFC2141 and RFC2616 specs and Microsoft's Response.Redirect Method documentation in an effort to answer the following question confidently.
Given this line of code:
Response.Redirect("~/Foo.aspx");
And this resulting HTTP response (trimmed for context):
Status=Found - 302 Date=Wed, 24 Nov
2010 17:27:58 GMT
Server=Microsoft-IIS/6.0
X-Powered-By=ASP.NET
X-AspNet-Version=2.0.50727
Location=/MyWebApp/Foo.aspx
What name(s) most properly describes what has been placed into the "Location" header?
URL? URI? URN? URC? Which is it?

The objective of this component is to be able to forward whatever HTTP requests it receives to forward to a different server based on the parameters but keeping the URL and POST data intact. For example:
If the component receives
[URL]
It will return the response from either
[URL]
where XYZ can be valid name of the page. I think I can probably individually create each page to do a Response.Redirect but i am wondering if there is a more generic way to do this? In addition, is this something I have to configure on the IIS level rather than code level?

Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.

I want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?

I've a question about something I'm searching for,for too long! We've build an application from which an admin upload songs into a database. Then user can bought songs and download it individualy. The problem is that when user download MP3 songs with the code below, it works great in Firefox and Chrome but not in IE8 simply because WMP trying to open the songs and it just don't get it instead of having a "Save as" dialog? Any issue on HOW can i force to have the "Save As" diaglog? Note that I have not MP3 physicaly on server it's in database. So I can't direct link to song ...
Here's my code :
// Remove "specials chars"
foreach (char aChar in @"/:*?""<>| ") {
if (aChar == ' ') {
songNameAndExt = songNameAndExt.Replace(' ', '_');
} else {
songNameAndExt = songNameAndExt.Replace(aChar.ToString(), string.Empty);
}
}
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
HttpContext.Current.Response.ContentType = "application/octet-stream";
HttpContext.Current.Response.Headers.Add("Content-Disposition", string.Format("filename={0}", songNameAndExt));
HttpContext.Current.Response.OutputStream.Write(songData, 0, songLength);

I'm trying to query a database that contains information about a "ticket" using jQuery's .ajax() method.
$.ajax({
type: 'GET',
url: 'Preview.ashx',
data: 'ticketID=' + ticketID,
success: function (data) {
// 'data' should be a row from the database, so it should be like an
// array that contains each column of the row
// do stuff with this data
}
});
... so that all works fine. I'm having trouble with the data variable. On the server side, I do...
// get the ticket ID from the POST parameter
int ticketID = context.Request["ticketID"] != null ? Convert.ToInt32(context.Request["ticketID"]) : -1;
if (ticketID >= 0) {
// grab the data from the database, getInfo() will retrieve the row
// in the DB that corresponds to the ticket ID given, returning an
// ArrayList with all of the information
ArrayList theTicket = getInfo(context, ticketID);
// now, I need to somehow return this information so that I could deal with it
// in the 'success' callback function above
return;
} else {
// something went wrong with the 'newTicket' POST parameter
context.Response.ContentType = "text/plain";
context.Response.Write("Error with 'ticketID' POST parameter.
");
return;
}
return;
I've debugged this enough to be sure that the ArrayList contains the correct information. Now I just need to return it. How would I do this? How would I return the data in the ArrayList? Is it possible to structure the response so that I could do data.ID, data.otherColumnName, etc... in the callback function to access the different fields?

I've had a bit of feedback from some threat and vulnerability folks relating to websites returning HTTP 500 response codes. Essentially the advice is that all possible measures must be taken to avoid the server throwing a 500 (i.e. extensive form input validation) which is fine. However, the advice also suggested that attempts to compromise security by means such as inserting a tag into a random query string causing ASP.NET request validation to fire or manipulating viewstate also should not return an HTTP 500. Obviously the native framework behaviour is to interpret the request and possibly throw to a custom error page but even this will return a 500 response code.
So I'm after some thoughts on how to approach this. Is there any way to configure the app at either the .NET level or IIS level to return an HTTP 200 when a 500 is raised? Or does this become a coding exercise at global.asax level in one of the application events? Are there other consequences to consider? BTW, the rationale from the security side is that apps which return HTTP 500 may be viewed as "low hanging fruit" by bots randomly scanning for vulnerabilities and prompt further malicious activity. attempts I'm personally not convinced that changing response codes offers any real security gains but am happy to hapy to take the advice of the pros.

I have an asp.net appliction on the one server. There I've added code on server-side in Page_Load:
Response.AddHeader("key", "password-key-from-hotel");
On the client side I have a form:
<form ... action="www.link-to-another-domaint" >
<input type="hidden" id="asd" value="fgh" >
....
</form>
<script type="text/javascript">
document.forms[0].submit();
</script>
Then on the other domain - there is also my other application - I'm trying to get the hedaer "key" by this code:
Request.Headers["key"].ToString();
But there is no such header. Is there is a desicion? Where is my mistake?

In my application I need to set a http response header. I'd like to do this in web.config. but I dont'know if this is possible and I can't find it on Google. Solution Finally, after a long search I found the solution. Create a class with this code:
public class myHTTPHeaderModule : IHttpModule
{
#region IHttpModule Members
public void Dispose()
{
}
public void Init(HttpApplication context)
{
context.EndRequest += new EventHandler(context_EndRequest);
}
void context_EndRequest(object sender, EventArgs e)
{
HttpResponse response = HttpContext.Current.Response;
response.AddHeader("Content-Language", "*");
}
#endregion
}
(Don't ask me why to use this event, but it works..) Now add a line in web.config in the HttpModule section:
<httpModules>
<add type="namespace.myHTTPHeaderModule, assembly name" name="headers" />
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</httpModules>

I am working on a website that I inherited (ASP.NET and C#), and I noticed that in almost EVERY method in the code behind of the project pages (except some helper methods), the original author uses Response.Redirect() to redirect to a page (typically home.aspx, but not always).
What is the purpose of doing this? It seems unneeded to me - at least it doesn't appear to change anything the website is doing if I keep it in or remove it.

I've developed a component which processes online payments. At a specific point the user must be redirected to the selected acquirer web site for authentication. The acquirer itself suggests that there should be a web page which does it. Something such as the following,
<!--TakeOff.aspx-->
<html xmlns="[URL]">
<head id="Head1" runat="server">
<title>@</title>
<script type="text/javascript">
function Go() {
form1.submit();
}
</script>
</head>
<body onload="Go();">
<form id="form1" runat="server" method="post" action="/...">
<div>
<asp:HiddenField ID="MID" runat="server" />
<asp:HiddenField ID="Amount" runat="server" />
<asp:HiddenField ID="ResNum" runat="server" />
<asp:HiddenField ID="RedirectURL" runat="server" />
</div>
</form>
</body>
</html>
This page redirects the user and posts required arguments to the acquirer's web site. Prior to this page there is another page with a payment button (for example). In the click event of the payment button my component is instantiated and required calculation is done. Something such as the following,
protected void btnPayment_Click(object sender, EventArgs e)
{
try
{
var paymentProcessor = new NS.PaymentProcessor(/*required arguments*/);
/*...*/
NS.Result result = paymentProcessor.Calc();
Session.Add("PaymentProcessResult", result);
Response.Redirect("TakeOff.aspx");
}
catch (Exception p)
{
throw p;
}
}
What I'm going to do is to generate [TakeOff.aspx] page at run-time by the payment processor component instead of having static page (I mean aspx pages that are generated during development phase). The reason why is that we may have different acquirers and each acquirer requires its own arguments to be posted. So if the payment processor component generates aspx or even html pages at run-time we do not need recompile and redeploy the web application.
My problem is that I do not know how to generate aspx pages at run-time. I'm not an ASP.NET guru and all efforts that I've made using HttpResponse were in vain as the original page does not transfer the control to the generated page.

I have two very similar pieces of ASP.NET code that send a file in an HTTP Reponse to the client. They should cause the browser to prompt to save the file. The first one works, the second one doesn't. The HTTP responses as seen in Fiddler are below.
Working:
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 228108
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 4.0.30319
content-disposition: attachment; filename=Report.xlsx
Date: Wed, 05 Jan 2011 12:17:48 GMT
<binary data>
Not working:
HTTP/1.1 200 OK
Server: ASP.NET Development Server/10.0.0.0
Date: Wed, 05 Jan 2011 12:19:21 GMT
X-AspNet-Version: 4.0.30319
Content-Length: 228080
content-disposition: attachment; filename=report 2.xlsx
Cache-Control: private
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
Connection: Close
<binary data>
When the first one is seen in Fiddler the browser correctly prompts to save the file. When the second one is seen in Fiddler, nothing observable happens in the browser. Same behaviour in both chrome and firefox.
EDIT: ASP.NET code that produces the second response
Response.Buffer = false;
Response.ContentType = @"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AppendHeader("content-length", genstream.Length.ToString());
Response.AppendHeader("Content-Disposition", string.Format("attachment; filename={0}.xlsx", filename));
byte[] buffer = new byte[1024];
genstream.Position = 0;
int n;
while ((n = genstream.Read(buffer, 0, 1024) ) > 0)
{
Response.OutputStream.Write(buffer, 0, n);
}

I am using an SMS Gateway to make my application receive SMSs. For this, the SMS Gateway sends a request to one of the pages in my application with the message as a querystring parameter. eg.[URL]. Now after my page gets invoked, I need to send an OK response to the SMS Gateway so that it doesn't keep retrying to send the same message to my application again and again. I cannot figure out how to send the OK response.

How can I unit test an action which alters the Http Response object? I haven't been able to solve this. I can mock the object but can't see how I can check the value after the action runs. I set the Response.StatusCode when errors occur in ajax requests and need to check it has been set in the unit test. The only alternative I can see is to change all my actions to return json objects with a IsSuccessful flag or similar.

we're facing a weird and seemingly randomly appearing problem where the browser renders the complete, raw HTTP response (to a GET request) including all headers and the compressed content as text instead of just using the contents and rendering it. This happens for whole page loads as well as postbacks as well as page loads inside an iframe; for sure in Firefox 3.6.*, not sure about IE right now.
Our service is an ASP.NET 2.0 web app running on IIS 7.5, on our test machines we regularly have Fiddler running in the background (wondering if this might be part of the problem).
This behaviour occurs very rarely but we have started seeing this problem lately during our tests.
Has anybody encountered this problem before and knows what causes it and maybe even knows what to do about it?

I am trying to the following to return xml response from an http request
Code:
Try
Dim id As String = Request.QueryString("id")
Dim xmlOut As String = ""
cn.ConnectionString = "Data Source=192.168.1.2;Initial Catalog=db;Persist Security Info=True;User ID=sa;Password=pass"
dad = New SqlDataAdapter("select * from tbl where id = '" & id & "'", cn)
ds.Clear()
[Code] ...
Is there some other way to do this without having to resort to writing the xml to a temp file on C drive and reading it again to display the output ?

I have a flash image slider with a button below each image. When i press that button, the user is redirected to a new page where i add that image product to my cart. The problem is that after doing the adding, i want to redirect the user back to the initial page.
The code:
protected void Page_Load(object sender, EventArgs e)
{
addProductToBasket(getCategoryIdFromUrl(), getProductIdFromUrl());
Response.Redirect(Request.UrlReferrer.ToString());
}
note that in Firefox is working fine but in IE or Chrome it is DOWNLOADING the swf...If i comment Response.Redict(...) the user remains on this page so the click button is working well, only the redirect seems to be the problem.
Edit: The problem seems to be that Request.UrlReferrer keeps as link not the initial page containing the swf but the swf itself.
So, instead of doing redirect to:[URL] if does redirect to the swf contained on the Index.aspx page[URL]
Solved: with a session variable where i keep the initial page's url
