HttpRequest.Cookies Property

Updated: April 2009

Gets a collection of cookies sent by the client.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public function get Cookies () : HttpCookieCollection

Property Value

Type: System.Web.HttpCookieCollection
An HttpCookieCollection object representing the client's cookie variables.

ASP.NET includes two intrinsic cookie collections. The collection accessed through the Cookies collection of HttpRequest contains cookies transmitted by the client to the server in the Cookie header. The collection accessed through the Cookies collection of HttpResponse contains new cookies created on the server and transmitted to the client in the Set-Cookie header.

NoteNote:

After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the HttpRequest.Cookies collection, even if the response has not been sent to the client.

The following code example loops through all cookies sent by the client and sends the name, expiration date, security parameter, and values of each cookie to the HTTP output.

var arr1, arr2 : String[]
var myCookieColl : HttpCookieCollection 
var myCookie : HttpCookie

myCookieColl = Request.Cookies
// Capture all cookie names into a string array.
arr1 = myCookieColl.AllKeys
// Grab individual cookie objects by cookie name     
for(var i=0; i < arr1.Length; i++){
   myCookie = myCookieColl(arr1[i])
   Response.Write("Cookie: " + myCookie.Name + "<br>")
   Response.Write("Expires: " + myCookie.Expires + "<br>")
   Response.Write ("Secure:" + myCookie.Secure + "<br>")

   // Grab all values for single cookie into an object array.
   arr2 = myCookie.Values.AllKeys
   // Loop through cookie Value collection and print all values.
   for(var j=0; j < arr2.Length; j++){
      Response.Write("Value " + j + ": " + Server.HtmlEncode(arr2[j]) + "<br>")
   }
}
