I have a cookie that exists in both request.cookies, and response.cookies; I want to change the one in response.cookies and leave the one in request.cookies to its original value; is there a way to do that? or at least, do you have something to read about

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.
I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?
View 1 RepliesI'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'd like to have a utility function that conditionally updates my request and response across several pages in my site.
Using a standard .CS class doesn't seem to give me access to these objects. How can I (generall speaking) create a utility function that checks for a cookie and update it across multiple pages?
It cannot change image when i using response.redirect cod as below

Response.redirect("A.ZIP")
I inherited a old WSE 3.0 service. I am building an ASP.NET client for it. It is returning a MTOM response so my client is complaining. Does anyone know of a way to change the response type to XML? Or change my client to accept MTOM? I just want this crap to work.
View 2 RepliesI am trying to change the text of a asp:textbox and collapse some ajaxToolkit:CollapsiblePanelExtenders within some ascx controls on my page as well as output a dynamically generated file. I have no problem collapsing the CollapsiblePanelExtenders and changing the text of the textbox from the codebehind or outputting a file. The problem arises when I want BOTH of these events to happen on the same postback. Unfortunately using Response.Write negates all of the other changes to the page.

I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
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.
View 5 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
I have written simple HttpModule. context.Response.Output.Write is working fine. but not context.Response.Write().

View 2 Replieswhat is difference between Response.write and Response.output.write
View 2 RepliesI'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?
How to handle cookies in asp.net?
View 5 RepliesOn my content page I have the code (in page_load):
if (Master.pageAction == "remove")
{
int removeProductID = int.Parse(Request.QueryString["ID"]);
int removeOptionID = int.Parse(Request.QueryString["optID"]);
Master.myBasket.removeFromBasket(removeProductID, removeOptionID);
//Response.Redirect("viewBasket.aspx");
}
The function remove from basket is defined as:
// Removes item from a basket
public void removeFromBasket(int itemsID, int optionsID)
{
Page myPage = (Page)HttpContext.Current.Handler;
this.setCookieString("");
myPage.Response.Write("done");
}
And it calls:
// Sets cookie date
public void setCookieString(string cookiesData)
{
Page myPage = (Page)HttpContext.Current.Handler;
HttpCookie basketCookie = new HttpCookie("basket");
basketCookie["items"] = cookiesData;
basketCookie.Expires = DateTime.Now.AddDays(7d);
myPage.Response.Cookies.Add(basketCookie);
}
I use the setcookiestring function on other pages and it works fine, but this function (removing from the basket) isn't setting the cookie! It is writing "done" to the top of the page, so the functions are executing.
No warnings, no errors, it's just not updating the cookie.
I want to use session object in my web app.I want to store some cookies too(Some custom informations) .How can i use both without the URL not being modified like [URL]
In my ASP.NET page,I am setting some session variable
Session["customerId"]="Some name";
Then i am trying to set some value in cookie
[code]....
In this page now i can access the sesion variable values,But when i m being Redirected to another asp.net page, I am not getting my session values there.Its seems like Its being lossed.
I would like to encrypt cookies in ASP.NET.
I have followed the method in this article, but it has the drawback that is uses reflection on an internal method. This has caused it to be flagged in a code review -- it is not future-proof as the internal implementation may change.
Is there a method with identical functionality which doesn't require using encryption on internal methods?
I am using .NET Framework 3.5 SP1 (Assume I cannot change framework versions)
I configure IE8 to block cookies.
