In my web application I wants the java script to clear the cache when the user close the browser. The javascript should listen to the event and clear the cache. Can anyone please provide me sample code or any useful link? Technically is impossible. What you can do instead is to tell the browser to not cache the page by using the following meta tags: <meta http-equiv='cache-control' content='no-cache'> <meta http-equiv='expires' content='0'> <meta http-equiv='pragma' content='no-cache'> Here is an article for reference http://www.htmlgoodies.com/beyond/reference/article.php/3472881 Narendra For

My code is pasted below. In the callback method, I set the user, but when I redirect to '/' the user is no longer available. I'm using passport and client-sessions.

If I store contents of a text file in a session variable in php, will it stay in memory for the period of that session? I have a small project where I need to perform searches in that specific text file which is just over 1mb. I'm thinking of using a session variable if it stays in memory, so that I don't have to read this file again and again. No, sessions will be stored default in files (e.g. in /tmp). Of course, you can use the memory with for example memcached. It's also possible to use a database for sessions. But, if you have enough memory, store your sessions in memory (very fast).
