I've tried to write my own HttpModule (IHttpModule) that adds a Header like that:
public class MyModule: IHttpModule
{
public void Init(HttpApplication c)
{
c.BeginRequest += delegate{c.Response.AddHeader("MyHeader", "MyValue");};
}
public void Dispose(){}
}
and tried to read in a aspx page like that:
var x = Request.ServerVariables["MyHeader"];
I have a very simple query. I have added custom header to my website. Now I want to read the custom header. I am using IIS 6.0 on windows XP. I have already tried using using the Request.ServerVariables and and Request.header method. But none of them give me the custom header added to website.

View 2 RepliesI am trying to call a webservice that requires me to authenticate and then pass the session id returned from the authenticate method to subsequent web service calls. The session id has to be passed as HTTP request header. So I tried using the following code to add the session id to a HTTP request header:
System.Collections.Specialized.NameValueCollection headers =
HttpContext.Current.Request.Headers;
Type t = headers.GetType();
//get the property
System.Reflection.PropertyInfo p = t.GetProperty("IsReadOnly",System.Reflection.BindingFlags.Instance
| System.Reflection.BindingFlags.IgnoreCase | System.Reflection.BindingFlags.NonPublic
| System.Reflection.BindingFlags.FlattenHierarchy);
//unset readonly
p.SetValue(headers, false,
null);
//add a header
headers.Add("Cookie",
"SID=" + sessionId );
The header is supposed to be called "Cookie" and the SID contains the session id. The problem is the last line in the code above gives an exception saying "Operation is not supported on this platform". I am running this code on my dev machine with with Windows XP Professional Service Pack 3 and IIS 5.1. I haven't been able to find any solution to this problem after days of searching. I also tried to deploy my web app on IIS directly but had the same error.
I could use late events such as EndRequest and put inside Response.Write but this way whatever I'm adding would come after the /html tag and the HTML won't be well formed.
View 1 RepliesI need to pass api key in custom http header ('X-ApiKey') and pass to another page. The second page will read that api key and do further processing. If api key is not passed in, it will redirect to error page.
I tried this way, but it didn't work.
In First.aspx page
Response.AppedHeader("X-ApiKey", "xxxxxxxxxx");
Response.Redirect("Second.aspx");
In Second.aspx page
string apikey = Request.Headers.Get("X-apiKey");
but X-apiKey is not passed in in second.aspx http header and ended up redirecting to error page.
Scenario: I have a bunch of web applications for which I want to add a simple ping functionality via http handler. Example: [URL]
Problem: For some of the applications this approach does not work becasue of custom HttpModule. These modules have some depedency on either authentication or some other processing logic due to which it makes the request invalid.
I am trying to find a solution to get this ping functionality work without making any changes to existing HttpModules.

View 2 Repliesas subject, how can i read Response Headers inside an httpmodule?
i need the "Content-encoding" header value.
i am making a Website with c# and ASP.NET 3.5, i just made an HttpModule to handle the NHibernate Session Life (Open and close).
I added it to the web.config and everything works fine. (all the query, code, etc working fine) except that CSS file of my masterpage is not loading !!
Scenario:
I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header.
I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the
gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,

View 3 RepliesWe are implementing a single sign on mechanism in an enterprise environment, where the token is shared between applications using HTTP header. Now, in order to do the integration test, I need to write an application to simulate this. Is there any way in ASP.NET where I can redirect to another web-page and pass a custom HTTP header in the process?
View 3 RepliesI 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:

<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?
Is it at all possible to use IIS7's rewrite capability in web.config to strip a particular HTTP header from a client request?We have an application that makes an HTTP POST to our website, and apparently the request contains the HTTP Expect header. Previously this was not a problem, but we've switched hosts and now the site is returning HTTP error 417 Expectation failed. So the real solution is to fix the software so it doesn't send the Expect header, but that can't happen soon enough for the folks in charge, who'd like to come up with an immediate web-based fix.I've used ISAPI_Rewrite before and I've read that it can strip a header, and the new host claimed they had ISAPI installed... but that seems to have been a lie, as I cannot get it to work, and support's only response on the subject is "use IIS7 Rewrite instead."

View 1 RepliesFirst, a little background. I have written a custom HTTP compression module for ASP.NET. My development machine has Windows 7 Ultimate, which comes with IIS7. My production environment uses IIS6.
The problem I'm having is, Resource Expert Droid (redbot.org) tells me that I need to add a header to my response to properly support compression: "Vary: Accept-Encoding"
On IIS7 in integrated mode, it works properly. However, in classic mode, which is how my application ultimately runs, I cannot get my code to output this header using any of Response.AppendHeader(), Response.Cache.SetVaryByCustom(), or Response.Cache.VaryByHeaders.
I am attempting to set the content-type of an asp.net .ashx file to text/plain.
When I run this through the ASP.NET Development Server, the content-type is properly set. When I serve it through IIS7, however, the content-type (and any other header values I set) don't come through (it came through as text/html).
The only value set in the HTTP Response Headers section of IIS Manager is the X-Powered-By attribute. I tried setting the content-type here, but that didn't work. But if I removed the X-Powered-By attribute, it was removed from the header.

I got the error when I called a webservice
---- Server did not recognize the value of HTTP Header SOAPAction: http://tempuri.org/GetBestBidOfferData.
The odd thing is that I have several methods in this webservice, and only two of them got me the error message. It used to work, but then gave me the error message after i added some other methods to the asmx file.
The namespace should be the same for all the methods. One more thing to note is: these two methods had return data type DataTable before, and I changed it to DataSet. It should not affect anything, I assume.
There are two applications "Sender", "Receiver"."Receiver" is a asp.net page, running in a serverSender" is not an asp.net page and running in some other server."Sender" is passing a string (eg. userName) through http header."Receiver" is reading the string from http header as followsRequest.Header["userName"].How to pass values through http header? Can I have some samples?
