A persistent cookie is stored in a file on your computer’s hard disk. It remains there after you close your Web browser. A persistent cookie will be picked up by the browser and included in HTTP requests for the Web server, where the cookie came from.
What are persistent cookies?
Persistent Cookies are stored on a user’s device to help remember information, settings, preferences, or sign-on credentials that a user has previously saved. This helps create a convenient and faster website experience. These cookies have an expiration date issued to it by the webserver.
How long do persistent cookies last?
Persistent cookies are stored in your webbrowser once you closed it. It can be used to track users or just to let them stay signed in (as may know from many webapplications). Those are stored as long as a webpage choose to (Google even used to set that date 30 years in advance!).
Cookies are small text files that are stored on your computer when you visit certain Web pages. Non-persistent cookies (also called per-session cookies) are temporary and are not placed on your system’s hard drive. They are automatically discarded when the Web browser is closed.
How can you tell if a cookie is persistent?
If a cookie does not contain an expiration date, it is considered a session cookie. Session cookies are stored in memory and never written to disk. When the browser closes, the cookie is permanently lost from this point on. If the cookie contains an expiration date, it is considered a persistent cookie.
Can we delete persistent cookies?
Some cookies will automatically be deleted after your website session is over (known as session cookies). Others, known as persistent cookies, may be removed after a few days or may be coded to automatically delete after a few thousand years.
Since the data in cookies doesn’t change, cookies themselves aren’t harmful. They can’t infect computers with viruses or other malware. However, some cyberattacks can hijack cookies and enable access to your browsing sessions.
Do cookies stay forever?
The duration of a cookie can be set when the cookie is created. Other cookies are ‘persistent cookies’, meaning they survive after your browser or app is closed and can be used by websites or apps to recognize your computer when you re-open your browser or app later.

When does a persistent session cookie expire?
When a session cookie whose values contain sensitive data doesn’t expire with the session, it becomes a Persistent Session Cookie, introducing a security risk. Instead of expiring when the web browser is closed as session cookies do, a Persistent Session Cookie expires at a specific date or after a specific length of time.
A cookie may persist only for the duration of the session (or an even shorter period). If a cookie is valid, it will be passed along with the HTTP request to the domain that it originated from.
