Hypertext Transfer Protocol ( HTTP) sessions.Other kinds of sessions include the following: This is considered a session because it is a series of interactions with the website requiring a data connection. Here, a session begins when a user first requests a page from a web server and is completed when that browser has sent over all the packets of information the server requested, such as when a user logs in to a website. For instance, when a user signs in to a web service, the session is essentially an exchange of information that results in the user signing in and the server storing this information for later use.Īnother kind of session is a browser session, which is when someone makes a request to a web server. If those are OK, the server authenticates the message.Īlternatively, the interaction may not involve a request or response between the two parties. The message, it decrypts it using that same symmetric key to check her nameĪnd timestamp. Timestamp using a randomly generated session key. In this example, Alice encrypts a message she is sending with its current
