Download a file using a password

Hello everyone, I would like to make a "download" section on a website, where the user will enter a password in a text field and this will initiate a respective file download. For example if they type "password1" and press enter, the download of "file1" should begin.

Any instructions/suggestions would be very helpful.

Thank you

this would be ideal work for Jacascript. =] just go to Javascript.com and checkout there codes.

Kenny, thank you for your reply. This is how I figured it out finally (using javascript).
Here is the code I used in case someone needs it.

<!--//
function pasuser(form) {
if (form.pass.value=="your password") {
location.href= "name of the file"
} else {
alert("Invalid Password")
}
}
//-->
</script>

<form name="download">
<input name="pass" type="password">
<td><div align="center">
<p>
<input type="button" value="Download"
onClick="pasuser(this.form)">
</p>
</div></td>
