Password protection


I am developing a web application and need it to protected by passwords. I was wondering if there was any way in which the users could create and save their own passwords ?

The other problem that i am thinking about it is... if the password protects and when entered correctly takes the users to is there any way that when the user types manually in the address bar it will ask him for the password...

thnks for all the help in advance..

You have to do security on the server side. What do you have access to on the server?

yes this is possible.

you can use .htaccess and .htpassword, but this is harder to let the users create their own password. (don't know what the effect is of a password protected area when users can create their own pass...)

or you can use a PHP script for this

short explanation of the PHP script:

create a login form, and call this script: (be sure the username and password fields are called: username / password)


$username = $_POST['username'];
$password = $_POST['password'];

//build query
$query = "SELECT * FROM users
   WHERE username='{$username}'
   AND password='{$password}'";
//execute query
$result = mysql_query($query);

//check if there are results
if(mysql_num_rows($result) > 0){
   $_SESSION['username'] = $username
   header("Location: index1.php");
} else {
   die("Sorry, no login details found");

the on top of every page:

   header("Location: loginform.php");
   header("Location: loginform.php");

something like this??...

The server i am using is the websphere application server and have full access to it...
then you can maybe work with .htaccess if the webserver app is apache...

otherwise you will have to use a server side scripting language
no objections... author gave no more comments so think it is solved.
