Response.Cookie Client Or Server/where Does The Cookie Saved? On Client Machine Or Server Machine?
Mar 7, 2011When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?
EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
[code].....
I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.
Scenario:On Page_Init() on code behind. I create a cookie using Response.Cookie.Add(new HttpCookie("MyCookie", "cookieValue"));.
On Client side, I'm trying to read the cookie saved from code behind on page load using the snippet above, but it returns undefined

Different Users Get The Same Cookie - Value In .ASPXANONYMOUS?
Mar 15, 2010My site allows anonymous users. I saw that under heavy load anonymous users get sometimes profile values from other users.
I first delete my cookies and get a valid unique value in the cookie value .ASPXANONYMOUS. After a couple of requests I get a new value for .ASPXANONYMOUS which is already used by another user. I see in my loggs that there are always a couple of users who share the same value in .ASPXANONYMOUS.
I can see in the my logs that 2 or more users realy get the same cookievalue for .ASPXANONYMOUS even if they have different IP.
Here is the htttp traffic. In the second image the changing cookie is shown (You have to display the image full size do be able to read the log):
One of the many requests that work ok:
Then there is this one request that changes the cookie
Then the new cookie is used
Just to be safe I removed dependency injection.
I dont use OutputCaching.
My web.config has this setting for authentication:
<anonymousIdentification enabled="true" cookieless="UseCookies" cookieName=".ASPXANONYMOUS"
cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" />
<authentication mode="Forms">
<forms loginUrl="~/de/Account/Login" />
</authentication>
UPDATE
I saw now that the http-traffic I showed is perfectly valid. A changing value in .ASPXANONYMOUS is something that happens because the cookie gets refreshed. The value contains AnonymousID and a Timestamp.
This does not lead to users having the same value in .ASPXANONYMOUS under normal conditions.
The problem realy is, that whenever the cokies get set from the AnonymousIdentificationModule, then there is a chance that a couple of user get this cookie. Setting a cookie in my application doesnt have this strange sideefect.

Web Forms :: Warn User When Leaving A Page With Changed Data?
Jan 28, 2010I'd like to know how I can warn a user when they're leaving a page where they've changed data (i.e. "You have unsaved data on this page, are you sure you want to abanon it?"). For example, the page has a few dropdown lists, some textboxes, etc. I'd like to warn them if they try to leave the page before saving the data. How can I do this? To add to my confusion, I also have a dropdown menu control (skmMenu) on the page that doesn't seem to have any events I can tie into.

HttpCookie hc = new HttpCookie("HiddenColumns");

View 3 RepliesWCF / ASMX :: Cookie Refuses To Get Set When Asking For A Cookie From Webservice
Jun 8, 2010I'm trying to use a webservice that first expects the clients to login, to retrieve a cookie to re-use.
This is done through a login(string user, string pass) method on the webservice.
Doing this through a browser works fine, we get a cookie, and we can see the cookie via Fiddler or whatvever proxysniff thingy.
Time to do the same in ASP.Net, so we use the WSDL and generate a nice proxy class, and it works fine to call the login() method, but Never Ever does a cookie get set !
I already used the "cookiejar" technique - which means i create an instance of a CookieContainer and assign it to the proxyclass like this;
var cookies = new CookieContainer(3);
How To Launch The Download Of A File Without Leaving The Current Page
Mar 2, 2011How can I force the download of a file on a ASP.NET page using datas from that page's ViewState?
Response.ClearContent();
Response.ContentType = "text/plain";
Response.AddHeader("Content-Disposition", "attachment; filename=" + "example.aaa");
Response.Write( this.ViewState["stuffs"] );
Response.End();
But if I do that the current page will be erased and return blank to the user.
Other examples says to create "download.aspx" and request it by javascript, but on a this new page I won't have access to the ViewState data of the first page.
The point is, how can I create a file, launch the download and don't lose the current page status?
