how to generate a countdown timer for 20mins even if the user refresh the browser

how to generate a countdown timer for 20mins even if the user refresh the browser. This is for a online test so that even the user refresh the broswer, the test remaining time is still there

I'd probably say set a cookie when the user starts the test, and check against that.

how?

You'd have to user a server side language such as PHP, CGI, or ASP. Last I knew (and it has been awhile), JavaScript has no cookie capabilities, even though they are both client side.

javascript does have cookie abilities ;)

I suppose I'm going to have to re-educate myself, then. :)
