i can hash user-entered password, i'm unable find out how compare stored hash , new hash user-entered password. this hashing code: public static string calculatehash(string cleartextpassword, string salt) { //convert salted password byte array byte[] saltedhashbytes = encoding.utf8.getbytes(cleartextpassword + salt); //use hash algorithm calulate hash hashalgorithm algorithm = new sha256managed(); byte[] hash = algorithm.computehash(saltedhashbytes); //return hash base64 encoded string compared , stored return convert.tobase64string(hash); } how compare 2 hashes validate password? first, should store salt hashed value. next, when user trying authenticate login , password can use next scenario: retrieve user data database login (for example, getuser(login) ). user class should contains login, hashed password , salt. if there no user login, fail authentication. else execute calculatehash() password , salt user class retrieved

playing javascript closures end question cannot reach explain. (function() { console.log("inside closure"); //does not work }(foo)); it not work because foo undefined. referenceerror but if prior set var foo = undefined; works (tested on chrome , ff). it not same undefined set undefined? example in jsfiddle in javascript, 'undefined' 1 of primitive data types. represents type of object. var = undefined; var b; console.log((typeof(a))); console.log((typeof(b))); the output undefined both cases. if don't declare variable @ , try access it, error thrown following. tried access c not declared @ all. uncaught referenceerror: c not defined(…)

'";'); var_dump($b);

flow: - user visits page www.mysite.com/somepage/1 - user clicks on log out button or times out , logs out *user log out detected redirect home page save referer url *redirect /login?ref=$_server['http_referer'] (actual code test if set) - user sees login page , relogs - user redirected refere url saved in $_get['ref'] the aboe flow works perfect first browser tab , if user has multiple tabs open $_get['ref'] gets set same url set first tab. example: example: tab 1 : /somepage/hello/world tab 2: /another/page/1 when user logs out tab 1 gets redirected to: /login?ref=http://site.com/somepage/hello/world (correct) if user refreshes page on tab 2 gets redirected to: /login?ref=http://site.com/somepage/hello/world not correct, should redirect to: /login?ref=http://site.com/another/page/1 don't redirect anywhere. handle re-login process on same url user on. keep url of every tab , browser window intact.
