4/14/2023 0 Comments Use session![]() Once a web developer accrues enough information on how users traverse their site, they can start to create very personalized, engaging experiences. Every time a user takes an action or makes a request on a web application, the application sends the session ID and cookie ID back to the server, along with a description of the action itself. To avoid storing massive amounts of information in-browser, developers use session IDs to store information server-side while enabling user privacy. Why is a web session used? (Web session use case examples) By mapping a single cookie ID to multiple session IDs, developers and analysts can get a clearer picture of how visitors interact with their web applications. A web session ID is unique to a specific visit, while a cookie is unique to a specific visitor and thus (developers hope) remains the same through multiple web sessions. Server logs typically contain both the session ID and cookie ID of a visitor. For example, a cookie may store information such as your name and preferences that it gathered when you filled out a form, then use that information to populate pages you visit throughout one or multiple web sessions. Cookies can be used for authentication, storing site preferences, saving shopping carts, and server session identificationīy knowing who is visiting a site and what they’ve done before, web developers can customize pages to create a personalized web experience. A cookie identifies, often anonymously, a specific visitor or a specific computer. While they are closely related, they are not the same thing. More specifically, session IDs and cookie IDs are confused. Sessions and cookies are sometimes conflated, creating confusion. If a user enters the site from one marketing campaign, leaves, and then returns via another marketing campaign.Ī cookie is a small piece of data from a web site that is stored on a visitor’s browser to help the website track the visitor’s activity on the web site.Also, Google Analytics sessions can expire on a campaign basis.Google Analytics sessions can expire on a time basis.There are two methods Google uses to expire an account: What is a session on Google Analytics?Ī session on Google Analytics begins when a user visits a site. Depending on the site, a developer may define a web session as short as five minutes or as long as 1,440 minutes (an entire day). The code that initializes a session also includes an expiration, so a single session never lasts beyond a certain duration, at least as far as the web property is concerned. It’s meant to represent the time between a visitor’s first arrival at a page on the site and the time they stop using the site. “Session” is the term used to refer to a visitor’s time browsing a web site. This session ID is passed along with any HTTP requests that the visitor makes while on the site (e.g., clicking a link). To track sessions, a web session ID is stored in a visitor’s browser. Websites use a session ID to respond to user interactions during a web session. Any interaction that you have with a single website is recorded as a web session to that website property. This could include your search engine searches, filling out a form to receive content, scrolling on a website page, adding items to a shopping cart, researching airfare, or which pages you viewed on a single website.
