What Does Session Cookie Mean?
A session cookie is a file containing an identifier (a string of letters and numbers) that a website server sends to a browser for temporary use during a limited timeframe.
Session cookies are enabled by default. Their purpose is help individual web pages load faster and improve navigation through a website. Each time the browser requests a web page from the server, it includes the session cookie file with its request. The cookie lets the server know which page components the browser has already been sent, so the server doesn't waste time re-sending them. When the browser closes at the end of a session, the file is deleted.
A session cookie is also known as transient cookie. This type of cookie is stored in temporary memory and is only available during an active browser session. End users can adjust browser settings to decline session cookies, however this often results in a poor user experience.
