Sessions can store any amount of data in the server memory.Application and Session variables store values that are global rather than page-specific for either a particular user (the Session) or to all users (the Application). And also, most of the browsers limit the number of cookies to 20. There is a size limit for cookies data i.e. The session is secure because it is stored in binary format and transparent from the user. They are the way to transmit session ids by default.Įvery session is identified by unique session id.Ĭookies stores the data in text format so it is not secure at all. We use sessions for all the conditions or situationsĬookies do not have any id. We use cookies in certain specific conditions keeping in mind the security reasons. As soon as we close the browser, the session is terminated and the data is lost.Ī cookie expired depending on the lifetime we set for it.Ī session expires as soon as we close the browser.Ī cookie stores the data for future reference.Ī session is not able to store the data for future reference because when the browser is closed, the session is timed out. The non-persistent cookies are also termed as in-memory cookies and session-based cookies.Ĭookies are the text files that store the user data and information on the client-side.Ī session refers to a state management technique that stores the user data and information on the server-side.Ī cookie stores the information until they deleted from the browser.Ī session stores the data until the session is alive. Non-Persistent Cookies are the temporary cookies that get expired when their duration times out and hence have an expiration time.The permanent cookies are stored in the hard disk of a computer permanently. Persistent Cookies are also termed as permanent cookies that do not expire and hence do not have an expiration time.HttpCookie mycookie = new HttpCookie() Ĭookies are of two types- Persistent cookie and Non-Persistent Cookie.if we visit any website on the internet and our browser has enabled the cookies for that website then that website will implant a cookie in the client’s machine which preserves the data related to the user activity in the user’s machine.Ī cookie can be created using an object of the ‘HttpCookie’ class and then we store the values in a cookie in key-value pair. Cookies store the data in the cache memory of the client machine in a text file. Session_End( ) – This event is fired whenever a session of user times out.Ĭookies represent a client-side state management technique in Asp.net.Session_Start( ) – This event is fired whenever a new user visits the application i.e.The session state variables are declared as key-value pairsĪn important point to note is that there are two events associated with a session i.e. Here the session state variable name is “UserName” and we pass a value to it. We can declare a session state ‘variable as shown below: Session= “Rashmi” If the session id is different, every time a request occurs to the server that means different users are requesting. This session id is used by the server to recognize the user. Each URL sent to the server contains an id known as session-id. So, we need to maintain the state of a user, so that the server recognizes the user. Each time a user sends a request to the server, the server treats that request as a new request. Asp.net Session state is a state management technique to store and retrieve values for a while the user travels within the webpages of a web application or a website.
