Basically, it's a small file on the server which is associated with the unique session id. The default behavior when the 'Expire' is not set is to set the cookie as a session one. Forcing the web application to only use HTTPS for its communication (even when port TCP/80, HTTP, is closed in the web application host) does not protect against session ID disclosure if the Secure cookie has not been set - the web browser can be deceived to disclose the session ID over an unencrypted HTTP connection. 4. If set to “/php/”, the cookie will only be available within the php directory and all sub-directories of php. Instead, it's the browser's responsibility to handle new cookies being set (if applicable to the current URL). SESSION EXPIRY. Cookies can have an expiry time, if it is not set, then the cookie expires when the browser is closed; Sessions are like global variables stored on the server; Each session is given a unique identification id that is used to track the variables for a user. (Firefox doesn't complains, btw.) But it doesn't look like my browser is setting the cookies. Thus, you need to call session_set_cookie_params() for every request and before session_start() is called.. Which is defined by the setting session.cookie_lifetime in php.ini. Unless they are HTTP-only, new cookies will be available through document.cookie. This function updates the runtime ini values of the corresponding PHP ini configuration keys which can be retrieved with the ini_get(). Since it appears you are redirecting the user to the member's only page using the Location header on the same page the session is initiated, the PHPSESSID cookie will not be set. A PHP session is much like a normal session which ends when the user closes their browser. Cookie or Session Variable not being passed I had this problem a few months ago and Jason called me - then after about an hour of messing around, I think he got it to work by making the cookie name all Caps. Set cookie parameters defined in the php.ini file. So yes, sessions are a better place to store sensitive information. However, to identify which user is which, a unique session ID will be generated and saved in a cookie. To fix it just don't put any expire at all. The information stored in the browser cookie has to bounce back and forth with each request so that the server knows who the user is. By default, it is equal to 0 which means "until the browser gets closed". EDIT: If I do document.cookie = 'JSESSIONID=xxxx;Path=/' in the console, and refresh the view. Both cookies and sessions must be started before any HTML tags have been sent to the browser. If you're having problem with IE not accepting session cookies this could help: It seems the IE (6, 7, 8 and 9) do not accept the part 'Expire=0' when setting a session cookie. If the cookie was set for Path / it means that it is sent along all the requests targeting the domain for which it was set, e.g myexam.ple/customers. For example, storing the users’ name, email, and ID in the session upon logging in. Please note: Setting nonzero value for session.cookie_lifetime could be not safe. The default value is the current directory that the cookie is being set in HTTPOnly: If set to TRUE the cookie will be accessible only through the HTTP protocol (the cookie will not be accessible by scripting languages). The problem with PHP sessions all comes down to performance and caching issues. But you could set the session cookie lifetime to some fixed value (in seconds). Path is not Matching. The effect of this function only lasts for the duration of the script. A PHP session handler is a mechanism which instructs PHP how it should manage sessions. The default session handler is a file system, and it means that PHP stores sessions on the disk.
