Question

I want force users to first click on some links and then go to a specific address. How can I terminate traffic sources that are direct in the second page? Or is there any way to only accept requests that are from specific a url?

Note: if there is something wrong, I want the page not to be viewable.

Thank you

Answer 1

What you could do is use the document.referrer property, and check weather or not the url matches the first page. Something like this, perhaps:

if (document.referrer !== 'http://www.google.com')
{
    window.location.href = 'http://www.google.com';//redirect to first url
}

As Bergi pointed out in his answer: this kind of functionality is really better left to the server side. Though suggesting cookies is, as far as I’m concerned, not the ideal way of doing this, since cookies can be turned off client side, or WCS, tempered with.

Depending on which server side technology you’re using, it might pay off to read up on all tools you have at your disposal to play with the request the user sends to your application, and take appropriate actions accordingly.
