MVC :: OnActionExecuted - Server Cannot Modify Cookies After HTTP Headers Have Been Sent?
Apr 1, 2011
We have a basecontroller that has both an OnActionExecuting and OnActionExecuted. Occassionally, the OnActionExecuted will throw an exception 'Server cannot modify cookies after HTTP headers have been sent.'. This doesn't happen all the time, and we can't find a pattern to it. My guess, based on searching, is that filterContext is not always the current context. Is there a way to rewrite the Cookies.Add to get the current context, always? Or is the fact that we are in the ActionExecuted mean the headers will always already have been sent and we shouldn't be doing anything like this in the executed step?

I am creating a web application in C#.When my page loads I fire an asynchronous thread to process some data. Part of this processing is the updating of a cookie. However when I save the cookie to the response by System.Web.HttpContext.Current.Response.Cookies.Add(c) where c is the HttpCookie, I get the following exception:HttpException: Server cannot modify cookies after HTTP headers have been sent.

I am getting the following warnings on the Event Log for a Asp.Net WebSite running on IIS 7.
Exception information:
Exception type: HttpException
Exception message: Server cannot append header after HTTP headers have been sent.
at System.Web.Hosting.ISAPIWorkerRequest.SendUnknownResponseHeader(String name, String value)
[code]....
I tried to debug the WebSite but it just does not show in debugger. The web page which has got this issue contains the following.
Its a content page with a Master page.
It has a grid inside an UpdatePanel which is Triggered by a Timer.
On the specified time grid data is refreshed.
Everytime this happens we see a new warning in the EventLog.

I have an ASP.Net site (happens to be MVC, but that's not relevant here) with a few pages I'd like cached really well.
Specifically I'd like to achieve:
output cached on the server for 2 hours.if the file content on the server changes, that output cache should be flushed for that page
cached in the browser for 10 minutes (i.e. don't even ask the server if it's that fresh)when the browser does make an actual subsequent request, I'd like it to use etags, so that the server can return a 304 if not modified.
(note - time values above are indicative examples only)
1) and 2) I can achieve by Response.Cache.SetCacheability(HttpCacheability.Server)
I know 3) can be achieved by using max-age and cache-control:private
I can emit etags with Response.Cache.SetETagFromFileDependencies();
but I can't seem to get all of these things to work together. Here's what I have:
Response.Cache.SetCacheability(HttpCacheability.ServerAndPrivate);
Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
Response.Cache.SetETagFromFileDependencies();
Response.Cache.SetValidUntilExpires(true);
Response.Cache.SetMaxAge(TimeSpan.FromSeconds(60 * 10));
In particular:
can browsers do both 3) and 4) like that? When Firefox issues a new request after it expires in the local cache, it does indeed send the etag the server responded with before, but I get a 200 response.setting the variables like above, where would I set the duration of the output caching?

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 Have a specific set of HTTP response headers I'm trying to recreate in ASP.NET.
Here is how it looks in Fiddler (Raw):
HTTP/1.1 200 OK
Content-Length: 570746
Content-Type: audio/wav
Last-Modified: Wed, 19 May 2010 00:44:38 GMT
Accept-Ranges: bytes
ETag: "379d676ecf6ca1:3178"
Server: Microsoft-IIS/6.0

Here is how it looks on the Headers tab (same data. Different view)
I am trying to recreate the same set of headers (different values of course) with code, on an ASP.NET page. The biggest problem is with the cache settings and the ETag. It usually shows some "private" or similar cache setting and no ETag value, even though I'm trying to set it explicitly with
Response.Cache.SetETag

This has been bugging me for a while now. Whenever I try to share my website link on Facebook or another link-sharing site, the link-sharing site either removes the URL (like it doesn't recognize it as valid) or in Facebook's case - it can't retrieve meta-data automatically.
I'm pretty sure that it used to work. However, Googling / StackOverflowing for this problem is a difficult task, since I have no idea what possibly could create this problem.
I've tried to create a static .HTM file on my website, and that works fine: test.htm
My default home page is a classic ASP (yeah I know, PHP version in the works) which uses IIS 7 URL Rewrite module.
I've tried to check the resultcodes and headers for both test.htm and my default home page on this page: [URL]
This is the results:
test.htm
URL=http://www.orango.nu/test.htm
Result code: 200 (OK / OK)

In the web app (C#, ASP.NET) I am working on at the moment, the value in Request.Headers["Referer"] can determine things like custom style. I have created a custom page with a drop down menu to test this functionality. So when the selected index changes, the value selected should be set in the Request.Headers["Referer"] then will be redirected (Response.Redirect), the receiving page will then pick up the value in Request.Headers["Referer"] and adjust the styling accordingly. However I haven't been able to set value for Request.Headers["Referer"]. Is it possible at all?
Website 1 sets the value in Request.Headers["Referer"], e.g. www.xyz.com and before doing Response.Redirect to www.website2.com
Website 2 picks up value in Request.Headers["Referer"], in this case www.xyz.com and do what it needs to do, i.e. styling etc.

As far as I can see, whenever a filter's OnActionExecuted is called, it might be after an exception has been thrown futher down the request processing pipeline. So surely this means that one should always be checking to see if there's an exception in the filter's context within an implementation of OnActionExecuted?
Isn't this like pre-exceptions error handling where one would have to, say, check the result of a method call to determine if there'd been an error - of course opening up the possiblity that one might forget to do this?

I have never work with a repeater and after a lot of research I got to the conclusion that this is the control I need to use for what I have to do. I need display data but I will need 2 headers and after some sort of amount of records the headers will repeat again. In this page you will find an example of what I'm trying to do http://ratings.fide.com/view_source.phtml?code=45276 I don't know if a repeater is the right control but i thin it is.

I'm handling cookies using JavaScript to store some values in my asp.net web application.I use document.cookie to save some values (converted into a lengthy string). But i want that value to be accessible across all the pages in my application.When i try to get that value from a different page, i get the values pertaining to the document in the current URL.
In short i save the value in the cookie in http://myapp/doc1.aspx and want to retrieve it in http://myapp/doc2.aspx
So is document.cookie is pertaining to a single document scope? How can i save/read cookies across the site?
Update.This is how i get and set cookies
function getCookie(c_name)
{
try{ [code]...
But i'm getting different values for the cookies in different pages.

I'm working on an intranet system (.NET 3.5); the main pages are served up from a standard ASP.NET server. I would like to use Ajax on those pages to contact a WCF service running on a different machine, to retrieve data, do CRUD operations - the usual Ajax stuff.
The problem I'm trying to resolve is: can I take cookies which were set by the ASP.NET server, and include them on requests to the WCF service? If so, how?
My understanding is that JSONP bypasses XSS restrictions by "wrapping" the Ajax request within a standard <script src="MyAjaxCall?SomeData=SomeValue"> tag. With that in mind, it would seem I'm at the mercy of the browser as to which cookies (if any) will be included in MyAjaxCall. Since the cookies originate from the ASP.NET server, the browser likely won't include them in the call to WCF.
Since this is an intranet application, I cannot necessarily rely on domain wildcarding (*.mydomain.com) to make sure the cookies are shared across multiple machines - the client may well be accessing machines by their simple network name or even IP address directly.
edit: accepting Julian's answer, since using JS to manually grab a cookie's payload and jam it onto the URL seems like the only way to work-around the restriction (tho it feels somewhat inelegant :)

I'm trying to implement a SessionState server to allow multiple web servers to share the same state. At first this will be the different dev machines, and later it'll be the different web servers in the web farm.
So far, I'm making good progress I think, but one of the requirements has me confused. In order to implement this, I need to make sure that all web servers are using the same machine key.
This is a sample MachineKey taken from my local dev machine:
[Code]....
If we have a Session State Server deployed locally, do I need to ensure that all other machines using this service (specifically, the other devs working on the same project, and then when we deploy to the web farm) have the exact same entry in their Machine.Config files?
Or do I have to somehow generate a new machine key that can apply to all the machines?

I previously asked on StackOverflow how to parse XML downloaded programmatically by my ASP.net application. By this, I mean that the user visits https://www.example.com/page1.aspx. The code-behind for page1.aspx is supposed to somehow download and parse an xml file located at https://www.example.com/foo.xml.
I received good answers about how to parse the XML. However, I've been out of luck with being able to retrieve XML from my secure HTTPS server.
I am looking at a situation where https://www.example.com/foo.xml authenticates requests with a cookie. (third party system, not Forms Authentication). The answer I received to my question about how to download and parse XML suggested that I use the System.Net.WebClient class. I read that the WebClient class must be customized to work with cookies. Therefore, I wrote the following code:
public class WebClientWithCookies : WebClient
{
private CookieContainer m_container = new CookieContainer();
public CookieContainer CookieContainer
[Code]....
However, when the request is received at https://www.example.com/foo.xml, there are no cookies in the request, and so it doesn't work.

I have following query (against db2/400 data base using linked server).
SET @SQLSTRING =
'SELECT * FROM OPENQUERY( AS400SRV_MSDASQL,
''SELECT
glmcu as business_unit,
SUM(CASE WHEN ((date(digits(dec(gldgj + 1900000,7,0)))) >= ''''' + CONVERT(varchar(11),@DateFrom1,121) + ''''' and (date(digits(dec(gldgj + 1900000,7,0)))) <= ''''' + CONVERT(varchar(11),@DateTo1,121) + ''''') THEN glu / 100 ELSE 0 END) AS quantity1
from VGIPRDDTA.F0911
where glmcu = '''' 1000131'''' and
(glsub = ''''00200 '''' or glsub = ''''00315 '''') and
gllt = ''''AA'''' and
gldct = ''''JE'''' and
globj = '''' '''' and
glum = ''''CY''''
group by glmcu
order by glmcu'')'
The query works fine but I need to modify my selection for fields 'glmcu' (BusinessUnit) and 'glsub' (CostCenter). Instead of hard coding the selection I will need to retrieve the selection (and grouping) from another table.
Table layout:
BusinessUnit Group CostCenter
1000131 1 00200
1000131 1 00315
1000131 1 00320
1000164 1 00200
1000164 1 00400
1000131 2 04000
1000131 2 04400
So with the above table example the query should render 3 records.

I have been experimenting with code that will clear all of the cookies in an HttpContext.Response.Initially, I used this:
DateTime cookieExpires = DateTime.Now.AddDays(-1);
for (int i = 0; i < HttpContext.Request.Cookies.Count; i++)
{
HttpContext.Response.Cookies.Add(
new HttpCookie(HttpContext.Request.Cookies[i].Name, null) { Expires = cookieExpires });
}
this will error with an OutOfMemoryException because the for loop never exits - each time you add a cookie to the Response, it also gets added to the `Request.
