What's the difference between cookies, local storage, and session storage? They are all ways to store data in a user's browser but they each have different uses.

Cookies are now stored in my belly :)

@ARUCARDFTEPES 7 жыл бұрын

So make sure I got this right: document.cookie = "belly=true";

I think it's more like this: document.cookie = "path=/CupOf SleepyTimeTea/belly";

Great video! Liked how you summarized all in one table. I don’t think this is true though 1:37 cookies are not stored on the server. They can be set by the server with a response header (set-cookie) and client sees that header and store it in the browser. The other way is through javascript document.cookie. But yeah only on the browser last time I checked.

Stating that session expires on tab close is quite misleading, isn't it?

@Irzani938 4 жыл бұрын

But looking at my php backed. The session only destroyed once browser closed instead of tab close. Also, isnt session is kept in server side? Or ttheres type of session?

@jaker9007 4 жыл бұрын

😂😂 The same question I got. How can he access data in session?

@ThePascalSchneider 3 жыл бұрын

@@jaker9007 The browser session storage is different from php's $_SESSION. The php session array ist stored on the server and identifies the user through a cookie which is usually called "PHPSESSID" and it is created automatically if your script contains session_start(). So the actual data stored in $_SESSION is on the server and the PHPSESSID-cookie is just an identifier which is sent at every pageload through the http header.

@dysonlu 7 жыл бұрын

Are cookies really stored on the server too? I always thought they were stored locally, on the computer running the web browser. From what I read, there is another server-side storage type called "session", which is typically used in conjunction with the browser's cookies but not to be confused with browser cookies.

@BeauCarnes 7 жыл бұрын

They are stored permanently on the server but they are sent to the server with every request so they can be used by the server. Local and Session Storage are never sent to the server.

Why do you say that cookies and local storage can be access on any window? Are not they tied to a domain? I set a local storage in one tab and I couldn't see it in another

@3208nandu Жыл бұрын

Both tab has to be of same origin then and then local storage get accessible across different tabs

dude don't just show the code. try to explain what and why for each, if possible. You are creating coders, when you could create software engineers. Don't just write ifs, think about why are writting that if.
