How to prevent a webpage from opening directly?

I have a request-information component through which an user can submit his enquiry. When he submits the form, the thank-you page that I have created is shown to the user.

 

Now the scenario is such that say the thank-you page has an url: abc.com/xyz/thank-you.html But I don't wan't anyone and everyone to see the page when they simply hit the url instead they should see Server Error (500). The page should only come up when the user submits an enquiry.

 

How to stop the page from directly loading when I put in the url in the address bar?

Hi,

There are two ways to do it.

1. Client side - check if page has referer that means , the user is not hitting page directly, this can be done using javascript, If no referer then you redirect user to 404 page, put this in head section so no rendering is done.

document.referrer

2. From server side check the referer header , if null then set 404 or 400 but for this page should not be cached.

 String refererHeader = request.getHeader("referer");
if (refererHeader == null) {
        response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
        return;
    }

    Hi @arunpatidar ,

     

    Since I am very new to AEM, can you help me out by mentioning where exactly I need the 

    document.referrer

    if I am going with the client-side approach. Will it be at the component level JS or page component js?

     

    Thanks!

      You can put this code in head.js, so that check can be done early as possible.
