Capturing url exactly as entered to use as variable in flash movies

[drexcol]

Here’s what I’m trying to do.

i have a url for my website, let’s call it alphasite.com.

I have some other urls which I using as aliases for alphasite.com. Let’s call these bakersite.com, charliesite.com, etc.

1- I want to know the exact url that someone has entered so that i can
capture that as a variable and use it in Flash to load specific movies. So it someone enters bakersite.com, I want them to directly go to a specific flash movie in alphasite.com.

How do I accomplish this in PHP? Do I use $HTTP-HOST? Will that keep as a variable the original typed in url or will it convert to the actual site, e.g. alphasite.com?

2- Let us say I want to direct people to a specific page, e.g.

 alphasite.com/music.html

how can I capture that entire URL.

Thanks. Your help is greatly appreciated.

P.S. Incidentally, I cannot seem to find much on the various environmental variables such as $HTTP_USER_AGENT, $HTTP_FROM, $HTTP_ACCEPT, etc.
I would be useful to have a list of these and a brief description of what they can be used for.

Thanks again.

Sorry to be so general but I don't know the exact name of the variables since I have used them like once, but search http://www.php.net for the $SERVER variable array as I am 99% sure that array holds your answer.

OK I looked at the missing file error page from the apache web server and these are the variables it uses to capture the page that is being looked for:

$_SERVER['HTTP_REFERER'].$_SERVER['REQUEST_URI'].$_SERVER['PATH_INFO']

All you'd have to do is echo these with some test pages and I'm sure you'll figure it out.
