What is session and how it works?

You can define session as a session of connectivity between the server and the client — the session object holds data that correspond to a user’s session. Session is a server side state management technique that is used to store user specific information in the memory for later retrieval.

Cookies are sent by the browser to the server when an HTTP request starts, and they are sent back from the server, which can edit their content. Cookies are essentially used to store a session id. In the past cookies were used to store various types of data, since there was no alternative.

Where are sessions stored?

PHP Default Session Storage (File System): In PHP, by default session data is stored in files on the server. Each file is named after a cookie that is stored on the client computer. This session cookie (PHPSESSID) presumably survives on the client side until all windows of the browser are closed.

What is meant by session management?

Session management refers to the process of securely handling multiple requests to a web-based application or service from a single user or entity. Websites and browsers use HTTP to communicate, and a session is a series of HTTP requests and transactions initiated by the same user.

20 minuteNormally in ASP.Net the session cookies are set with a 20 minute timeout. That’s usually pretty good. Depending on your app, you may want a javascript timer as well. Otherwise the browser won’t understand when it’s logged out until a page refresh happens and sensitive data can be exposed.

What is session with example?

A session is a global variable stored on the server. Each session is assigned a unique id which is used to retrieve stored values. Whenever a session is created, a cookie containing the unique session id is stored on the user’s computer and returned with every request to the server.

What is the purpose of session?

Sessions are a simple way to store data for individual users against a unique session ID. This can be used to persist state information between page requests. Session IDs are normally sent to the browser via session cookies and the ID is used to retrieve existing session data.

What is the typical session identifier?

A session ID is a unique number that a Web site’s server assigns a specific user for the duration of that user’s visit (session). The session ID can be stored as a cookie, form field, or URL (Uniform Resource Locator). Some Web servers generate session IDs by simply incrementing static numbers.

Where is Session ID stored?

Session IDs can be stored as cookies locally at the client end. When a request is made to the server, the server transmits the cookie containing the session ID. The server has stored the session ID and associated information from the last session and makes it available to the client if the session ID matches.

How are sessions stored?

Client-side sessions use cookies and cryptographic techniques to maintain state without storing as much data on the server. When presenting a dynamic web page, the server sends the current state data to the client (web browser) in the form of a cookie. The client saves the cookie in memory or on disk.

How long is a session?

By default, a session lasts until there’s 30 minutes of inactivity, but you can adjust this limit so a session lasts from a few seconds to several hours.

SESSION is more secure than COOKIES. Because SESSION will destroy is data immediately and after closing the application. … The main difference between cookies and sessions is that cookies are stored in the user’s browser, and sessions are kept on server side.

Can session work without cookies?

You CAN use PHP sessions without cookies, as long as the browser identity is obtained somehow and yields a unique value (and this value is passed to the PHP session layer): session ID in GET (which is the “standard” PHP way if cookies are not allowed, and the “other” way you described).
