How can I detect if page was requested via a redirect?

Question

On a client\'s website there are loads of redirects going to a particular page. This page somehow needs to have a way detecting whether the request was direct (URI typed in

Answer 1

How about:

my $cgi = CGI->new;

print $cgi->redirect(
    'http://example.com/this/page/that.html?redirect=yes'
);

What ever mechanism you are using to distinguish between redirects can then look at the query string to decide. Of course, this does not prevent users from bookmarking the URL with the redirect=yes etc.

You could try the referer header, but that has its own problems.
