How to send all referral traffic without .htaccess?

Question

I have a website with two landing pages (www.abc.com):

• landing page- 1 =(www.abc.com/index.php)
• landing page- 2 =(www.abc.com/index1.php)

Conditions of landing page 2:

• robots can not be allowed
• referral traffic allowed for united states only (if anyone connects from another country the website will open the default page).

Note: Referral traffic means the traffic which we purchased from adnetworks.

How can we stop robots and how we can redirect the referral traffic from a selected country and how will we detect the country?

Answer 1

In your PHP script, you can always check the $_SERVER['HTTP_REFERER'] value and redirect to the appropriate page using:

header('Location: '.$pageYouWanToRedirectTo);
exit();
