    Change the header of a page depending on the source.

    We have two headers for a page. the firs header is displayed when we come to the page from site "X" and the second header is displayed when i come from site "Y". How can i check from which site i am coming to the page and accordingly display the right header? Please help me with code pieces.

    Thank you

          Wait a second: many ISP do not allow the user agent to write this field because it can easily be falsified. If it is set by the agent and you want to use it, fine, but never trust it for a second.

                  He's just saying that you can manually submit the referrer and trick the page to thinking another page requested it. So if your header_1 was public, and your header_2 was private, it would be reasonably easy to get to your header_2 by making a fake request name. Not exactly sure how it works, but just becareful what you put in your headers if you use that method, as they are not very secure.

                  Another way would be to check the logins... Do you use a login system? As in can people register on your site?
