ASP NET 2.0 Cookie

[icanhelp33]

I have a C# utility that runs in ASP website. When user logs in the
ASP code writes the cookie using Response.Cookie. I try to read the
same cookie in C#. I am unable to read it in C# code.

I am using Request.Cookies["cookiename"].Value.ToString(). I can read
the same cookie in ASP code.
If I say Request.Cookies("CookieName") in ASP that works fine..

re:
!I am using Request.Cookies["cookiename"].Value.ToString()

Try either of these approaches :

1.

if(Request.Cookies["cookieName"] != null)
Label1.Text = Server.HtmlEncode(Request.Cookies["cookieName"].Value);

2.
if(Request.Cookies["cookieName"] != null)
{
HttpCookie aCookie = Request.Cookies["cookieName"];
Label1.Text = Server.HtmlEncode(aCookie.Value);
}

Before trying to get the value of a cookie, you should make sure that the cookie exists;
if the cookie does not exist, you will get a NullReferenceException exception.

Notice also that the HtmlEncode method was called to encode the contents of a cookie
before displaying it in the page. This makes certain that a malicious user has not added
executable script into the cookie.

I know how to read the cookie. The problem is when I try to read it in
C# it always returns null. In ASP it returns the value of the cookie.

re:

!The problem is when I try to read it in C# it always returns null.

Then, either the code you're using doesn't read the cookie properly,
or the cookie isn't being set correctly.

Have you tried the code I posted to read cookies ?

As for setting cookies, here's 2 sample C# code fragments :

1.
Response.Cookies["userName"].Value = "patrick";
Response.Cookies["userName"].Expires = DateTime.Now.AddDays(1);

2.
HttpCookie aCookie = new HttpCookie("lastVisit");
aCookie.Value = DateTime.Now.ToString();
aCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(aCookie);

How are you setting the cookie ?
Are you expiring the cookie ?

I'm really not sure you can do that... ASP And ASP.NET are separate
engines... I'm even surprised you don't get an exception as from the point
of view of the C# utility (how do you run this one ? This is exposed as a
com object ?) there is IMO no current (ASP.NET) request...

You may want to elaborate a bit on your architecture and/or what you are
trying to do...

Or do you mean you just transfer control from an ASP page to an ASPX page as
Juan seems to have understood from your description ?

As you talked about a "C# utility" rather than about an ASP.NET page, I was
thinking that this "C# utility" was directly called from the ASP page during
the same request. As i said earlier you may want to elaborate a bit on your
architecture so that we are 100 % sure about how ASP and ASP.NET interacts
in your design...

Cookies should be able to read regardless
of the language/platform used to write them.

Typo alert...

That should have been :

Correct, though some languages like C# are case-sensitive, which may be the
issue here...

Make sure the Path property of your cookie is set. , e.g. "/". There are
minor inconsistencies in classic ASP cookies and ASP.NET cookies.

[Peter Bromberg [C# MVP]]

To be more specific:

Cookie Interop - ASP -->ASPX:

There is a change in cookie behavior between ASP and ASPX. In brief: If you
do NOT
specifically set a cookie path, ASP will automatically set the path to:
your web application's name --
"/AppName"
If you do NOT specifically set a path, ASPX will automatically set the path
to:
your server name --
"/"

To make ASP behave like ASPX, then add --
Response.Cookies("...").Path = "/" -- to your ASP code

To make ASPX behave like ASP, then add --
MyCookieObject.Path = "/AppName" -- to your ASPX code.
