Trouble removing cookies - .NET Framework

Nathan Sokalski

I am having trouble removing cookies that I created with my site. Here is
the code I am using to try and remove them:
If Not Request.Cookies ("username") Is Nothing Then
Response.Cookie s.Remove("usern ame")
If Not Request.Cookies ("password") Is Nothing Then
Response.Cookie s.Remove("passw ord")
Is there something I am missing here? Even after I do a Session.Abandon ()
the cookies still seem to be there. Is there another step that is necessary?
Thanks.

Nathan,

Instead of removing the cookies (I believe that just removes them from the
server memory and not the client) you should overwrite them on the client.

If Not Request.Cookies ("username") Is Nothing Then
Response.Cookie s("username") = ""
End If

Oh, and even an empty cookie may not be equal to "Nothing" because it is a
string you may need to test for "" instead.

I figured out how to remove them, which is to set the Expires property to
somewhere in the past and the use the Response.Cookie s.Add() method.
However, what is the point in removing the cookies from the server memory if
they get resent with every Request anyway?

Nathan,

I'm not certain about that myself... It really may just be the object they
chose to hook up cookies with. It looks like the object is ultimately
inheriting from something similar to arraylist (if it isn't arraylist itself
I didn't bother to check). It may not be that they intended Remove to even
be used. It may just have come along for the ride via inheritance.

cookie trouble - vb.net web page

by: Owen | last post by:

I have a web app that is a mixture of ASP and ASP.NET pages. Largely the only data passed between them is via the querystring, or by reading from a database.

In my ASP page, I created a cookie and put a value in it: Response.Cookies("MyCookieName") = "OriginalValue" Response.Cookies("MyCookieName").Expires...

I've created a quick set of test scripts, and I'm finding that cookies don't work as I would expect(i.e. the same as they do in original ASP. In original ASP I could set a cookie on one page, set another value to that cookie on a second page, then read them both back on a third page, but in .NET the second page overwrites the first. here are my three .NET test pages: setCookie1.aspx: Response.Cookies = "true";

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
