Checking if URL exists

[Gargoyle]

Is there a way in JavaScript to test if a webpage exists, for example
before redirecting a browser window to that page?

What I am trying to do is customize an acknowledgement page for
particular users depending upon choices they make when completing a
form.

You can try to load it with AJAX.

I don't understand what this has to do with the question.

Basically, I wanted to test if the customized page existed before
redirecting the user to that page.

Why wouldn't it exist? Is it maintained by somebody else?

It should exist, but just in case the page/file had been deleted (for
an old customer) I wanted to be sure.

If you have access to serverside scripting,
make a dedicated 404.asp [or the php equivalent] file
that reports to you where a file does not exist
and the referrer page is from your own domain.

That some browsers do not give a correct referrer,
is not that important, you'll just miss a few.
