Hello on my website i have a textbox on the first page. I want it so the users enter a specific password in the textbox, click the enter key on their keyboard and/or a button on the screen and then if the password for example eqauls "12345" then the user will advance to "http://www.mywebsite.com/secretpage.html".

Also since the above website is suppose to be a 'secretpage' i dont want the user able to just type that link on the addressbar and bypass my password. What can i do about this?
