Passing Cookies

T

Tom

I know how to create a cookie using the HttpCookie.
I know about setting its domain so it can be shared.


So I have created a cookie on web site A and set it to
expire in 10 minutes.

Now I am on web site B, in VS.NET C# and I want to access
the cookie created on web site A.

Is this possible?

Can anyone advise??

Here is the code:

DateTime dt = DateTime.Now;
TimeSpan ts = new TimeSpan(0,0,10,0);

HttpCookie MyUIDCookie = new HttpCookie("MyCookie", "some
value");
MyUIDCookie.Domain = ".mydomain.com";
Response.Cookies.Add(MyUIDCookie);

MyUIDCookie.Expires = dt.Add(ts);

Tom,

If the websites A and B are within the same domain, you can retrieve cookies
from the Cookies property of the HttpRequest instance available from the
Page's Request property.

Dimitria:

Yes, both web sites (A and B) are in the same domain.

And I tried these three attempts but "myCookie" always
returned null when I executed it on web site B in C#.

myCookie = Request.Cookies["MyPwdCookie"];
myCookie = HttpRequest.Current.Request.Cookies
["MyPwdCookie"];
myCookie = HttpContext.Current.Request.Cookies
["MyPwdCookie"];

HttpCookie myCookie = Page.Request.Cookies["MyPwdCookie"];

myCookie = HttpContext.Current.Request.Cookies
["MyPwdCookie"];


Can you advise further?

Hi Dmitriy,

As MSDN states, the cookies can be retrieved across the domains, please
refer to :

Jeffrey,

Thanks for pointing out the issue.

The article you have referred to reads:

"Before sending a request, the client browser checks to see if a cookie is
available containing a domain property that ***matches the tail of the fully
qualified domain name of the host specified in the requested URL**. If such
a cookie exists, the path property of the cookie is compared to the path
name component of the requested URL. If they match, the cookie is sent with
the request"

According to the fragment enclosed in "***"s, I beleive, the original
poster's websites A and B should have the same top-level domain name, such
as

app1.company.com

and

app2.company.com

and the client's browser, let's say IE to be specific, will never send a
cookie having its Domain attribute set to "app1.company.com" with a request
being sent to "app1.anothercompany.com"? Could you please elaborate if I am
mistaken?

Does anyone know if classic ASP Cookies object supports the ASP.NET
".domain" property?

Thanks

Hi Tom,

I found that you have asked if ASP.NET support the ".domain" property in
microsoft.public.vsnet.general queue with Subject:
"Cookie Domain Property"
And a colleague of mine has replied an answer to you, please follow up him
there, he will work with you.

Thanks for your understanding
