Gets a collection of cookies sent by the client.
Assembly: System.Web (in System.Web.dll)
'Declaration Public ReadOnly Property Cookies As HttpCookieCollection 'Usage Dim instance As HttpRequest Dim value As HttpCookieCollection value = instance.Cookies
ASP.NET includes two intrinsic cookie collections. The collection accessed through the 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.
After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the 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.
Dim loop1, loop2 As Integer Dim arr1(), arr2() As String Dim MyCookieColl As HttpCookieCollection Dim MyCookie As HttpCookie MyCookieColl = Request.Cookies ' Capture all cookie names into a string array. arr1 = MyCookieColl.AllKeys ' Grab individual cookie objects by cookie name for loop1 = 0 To arr1.GetUpperBound(0) MyCookie = MyCookieColl(arr1(loop1)) Response.Write("Cookie: " & MyCookie.Name & "<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 loop2 = 0 To arr2.GetUpperBound(0) Response.Write("Value " & CStr(loop2) + ": " & Server.HtmlEncode(arr2(loop2)) & "<br>") Next loop2 Next loop1
