Domain Forwarding

[CrapDice]

I have a fully-developed site hosted at companyQ, I also have a domain name registered with companyR that is "forwarded" to the root directory at companyQ.

Is there any way to change logo images depending on which domain a visitor accesses the site?

For instance-- if they arrive at ABC.com (hosted and registered via companyQ) the logo appears as ABC.gif however if they access XYZ.com (forwarded to the companyQ host but registered with companyR) the logo image appears as XZY.gif?

Basically, if people arrive to my site via ABC.com, then I want the logo to indicate as much. However if they arrive via XYZ.com -- which is just a masked forward to ABC.com -- the logo is different.

Mad props, and perhaps a wooden nickel , if you can solve this riddle.

It's very simple actually. If you are going to use PHP, you can simply use the referral option.

Using this feature of PHP: $_SERVER["HTTP_REFERER"], you can see which site the visitor came from.

If the visitor came from the site of companyQ, then set a function to change the logo, but if the visitor came from anywhere else, then just leave the logo at a default.

I hope this made sense
