A cookie is stored on the client's machine by their web browser software. To set a cookie, we include information in an HttpResponse that instructs the browser to save a cookie on the client's system. Here's the basic code for writing a Cookie in ASP.NET
Using System.Web;
Response.Cookies["BackgroundColor"].Value = "Red";
|
|
|
And to read the cookie back :
Response.Write
(Request.Cookies["BackgroundColor"].Value);
|
|
|
Note that for security reasons you can only read a cookie that was set within the same domain name.
Sometimes you may need a collection of stored items, such as user address details. In this case you could read in a cookie collection like this:
HttpCookieCollection cookies = Request.Cookies;
for(int n=0;n<cookies.Count;n++)
{
HttpCookie cookie = cookies[n];
Response.Write("<hr/>Name: <b>" + cookie.Name + "</b><br />");
Response.Write("Expiry: " + cookie.Expires + "<br />");
Response.Write("Address1: " + cookie.Address1+ "<br />");
Response.Write("Address2: " + cookie.Address2+ "<br />");
Response.Write("City: " + cookie.City+ "<br />");
Response.Write("Zip: " + cookie.Zip+ "<br />");
}
