Cookies allow developers to maintain the state of a user's interaction with a website. Web applications use sessions to store data between user connections. Cookies and sessions solve the problem of a stateless Web. This online video defines a stateless Web and offers a closer look at using cookies and sessions in Ruby on Rails 4 applications. Viewers will gain an understanding of how cookies and sessions help developers to understand user patterns and preferences.
…We mentioned Cookies and Sessions briefly backed when we talked about the Flash…Hash because Rails uses the Session to…store the Flash Hash values between request.…Now let's get a closer look at them.…One of the challenges of building web applications…is that the web is a stateless environment.…When web servers respond to request for pages,…each request is treated as a new request.…And the web server doesn't know, keep track of…or care about what previous request had been made.…It doesn't know what a user selected or clicked on previously.…It doesn't know if the user's even logged in or not.…
Cookies help us to solve the problem of the stateless web.…A web server can place a cookie file on the user's browser and store data in it.…With each request to that web server, the browser…will send along that cookie file with the request.…A cookie might track what the user last clicked on.…Or, it might include the user's location,…their language preferences, or their search settings.…And this allows us as developers.…
