# Cookies in ASP.Net
Cookie is a small [text file](https://www.mindstick.com/forum/2174/how-do-i-locate-a-particular-word-in-a-text-file) sent by [web server](https://www.mindstick.com/articles/23199/digital-personal-server-the-premium-web-server) and saved by [web browser](https://answers.mindstick.com/qa/95505/what-are-the-pros-and-cons-of-using-safari-web-browser) on client machine. [Cookies](https://www.mindstick.com/articles/40/cookies-in-asp-dot-net) are created when a user's browser loads a particular [website](https://yourviews.mindstick.com/view/87705/when-do-we-require-an-agency-to-drive-traffic-to-a-website). The website sends information to the browser which then creates a text file. Every time the user goes back to the same website, the browser retrieves and sends this file to the website's server.\
##### There are two types of cookies available in .Net
\
1. Non [Persistent](https://www.mindstick.com/interview/22840/what-is-the-use-of-persistent-store-coordinator-in-core-data) / [Session](https://www.mindstick.com/articles/12042/session-in-c-sharp) Cookies
2. Persistent Cookies
##### Non Persistent / Session Cookies
Non Persistent cookies are stored in memory of the client browser session, when browsed is closed the non persistent cookies are lost.
##### Persistent Cookies
Persistent Cookies have an expiration date and theses cookies are stored in Client [hard drive](https://answers.mindstick.com/qa/114546/how-to-troubleshoot-external-hard-drive-recognition-issues).
##### Example:
Following example will show how to store the Cookies and [Retrieve](https://www.mindstick.com/forum/34400/how-to-retrieve-form-values-in-controller-action) Cookies Data.
**1.** Create the UI in [ASP.Net](https://www.mindstick.com/articles/155/concept-of-asp-dot-net) as shown bellow
**2.** Now, switch to Code View and write the following codes
```
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { } //Storing the Cookies protected void Button1_Click(object sender, EventArgs e) { //Creating Object for HttpCookie Class and Named it "UserInfo" HttpCookie objCookie = new HttpCookie("UserInfo"); objCookie["UserName"] =TextBox1.Text.ToString(); objCookie["Password"] =TextBox2.Text.ToString(); //Specified time limit forcookie to accessed objCookie.Expires= DateTime.Now.AddMinutes(30); Response.Cookies.Add(objCookie); } //Reading data from Cookies protected void Button2_Click(object sender, EventArgs e) { HttpCookie objRequestRead =Request.Cookies["UserInfo"]; if (objRequestRead!= null) Response.Write(objRequestRead["UserName"] + " " + objRequestRead["password"]); else { Response.Write("Cookies has beenExpired"); return; } } //Reading all stored cookies protected void Button3_Click(object sender, EventArgs e) {
HttpCookieCollection objAllRequestRead = Request.Cookies; for (int i = 0; i < objAllRequestRead.Count; i++) { HttpCookie ck = objAllRequestRead.Get(i); if (ck != null) { Response.Write("Cookie Name "+"'" + ck.Name +"'"); Response.Write("
Cookie Value " + ck.Value); Response.Write("
"); } } }}
```
Cookies are stored for 24 hrs, if you have not specified any time limit for Cookies Expiration.
