what i need is: create a redirect page with diffrent content (in same url) depending on source url where visitor come! for exemple :

• Visitor X come from a href url www.example.com/page?u=target1.com
• Visitor Y come from ahref url www.example.com/page?u=target2.com

the redirect page for both visitors X and Y is www.example.com/redirect-page but with different content for the visitor X a (button) with a href button to target1.com for the visitor Y a href (button) to target2.com (sorry for my bad english, i hope get the right answer )
