Check if cookies are enabled

阅读更多关于 Check if cookies are enabled

I am working on a page that requires javascript and sessions. I already have code to warn the user if javascript is disabled. Now, I want to handle the case where cookies are disabled, as the session id is stored in cookies. I have thought of just a couple ideas: Embedding the session id in the links and forms Warn the user they must enable cookies if they are disabled (would need help detecting if cookies are disabled) What is the best way to approach this? Thanks EDIT Based on the articles linked, I came up with my own approach and thought I would share, somebody else might be able to use it

How do I create persistent sessions in PHP?

阅读更多关于 How do I create persistent sessions in PHP?

问题 I used session_start() to initiate a session in PHP, but when my browser closes, the session is gone.

Switching between HTTP and HTTPS pages with secure session-cookie

阅读更多关于 Switching between HTTP and HTTPS pages with secure session-cookie

问题 Update: Note that every website switching between unsecure HTTP and encrypted HTTPS pages, is inevitable prone to SSL-strip.

How does cookie “Secure” flag work?

阅读更多关于 How does cookie “Secure” flag work?

问题 I know that a cookie with secure flag won\'t be sent via an unencrypted connection. I wonder how this works in-depth. Who is responsible for determining whether the cookie will be sent or not? 回答1: The client sets this only for encrypted connections and this is defined in RFC 6265: The Secure attribute limits the scope of the cookie to "secure" channels (where "secure" is defined by the user agent). When a cookie has the Secure attribute, the user agent will include the cookie in an HTTP

What is the difference between session_unset() and session_destroy() in PHP?

阅读更多关于 What is the difference between session_unset() and session_destroy() in PHP?

If not, how do you accomplish this (destroy the session itself). Is it correct that neither of the two functions deletes the session

阅读更多关于 Why not generate the secret key every time Flask starts?

问题 When using sessions, Flask requires a secret key. In every example I\'ve seen, the secret key is somehow generated and then stored either in source code or in configuration file. What is the reason to store it permanently? Why not simply generate it when the application starts? app.secret_key = os.urandom(50) 回答1: The secret key is used to sign the session cookie. If you had to restart your application, and regenerated the key, all the existing sessions would be invalidated. That's probably
