Password protected HTML page

I want to restrict some pages on my web-site to users with a login and a password (much like the way I need to punch in my login name and password to use my Expert-Exchange account). How can I do this? Which tools do I need? Can this be done by HTML only?

You can do this by restricting access to the page on the server.

However what you can do with HTML only is:

<form name="theForm">
<input type="password" name="pwd">
<input type="button" value="Enter" onclick="location.href='document.theForm.pwd.value'+'.html'">
</form>

The name of the page is the password. Only someone who knows the password can find the page. Alternatively use the password as the name of the folder.

thing is - viewing the source code of the page reveiles the password and all...

No it doesn't.

The page contains the above script only. The name of the page is not included in the page at all.

No, it doesn't.  the source code doesn't show what you input in the fform.
On the other hand, knowing the password, you could go directly to the document, making the form superfluous.

OK here is something even smarter:
Have the form take you to a page that contains a meta-refresh / location.href= or even better a location.replace that will take you to your off-bounds page.

Thus the new page:

<head>
<script>
if(location.replace)
  location.replace("theRealPage.html);
else
  location.href=("theRealPage.html);
</script>
</head>

 The advantages now are:
1. you can change the name of this page whenever you like without upsetting links or anything else.
2. a casual passer-by cannot see the password by reading the URL.

The location.replace is the best but not supported by all browsers (javascript 1.1 supported by NS3+, IE4+).

Do you want to use Javascript where when a link to password protected file is clicked, a small new window pops up asking for password/username. If only when they are correct, it'll load the new page in the main window. By the way, where are yoou storing user anme and  passwords(I mean are you using any database?)
