Need some quick help with a htaccess redirect

[vetting]

Ok, I have the following link

http://www.subdomain.mysite.com/?itemID=65165654654

I need to redirect it through another site.

http://www.othersite.com/65165654654?refid=store
So I need to drop the ?itemID= and add another tag at the end.

I tried to get it to work but just couldn't get all of the parameters right. Thank you in advance for your help.

I'm not sure if you'll be able to do that with redirect in .htaccess... but you could do something like this with rewrite and a PHP page.

.htaccess...
RewriteEngine On
RewriteRule ?itemID=([0-9]+) go.php?itemID=$1 [QSA,L]
So this will look for itemID in the url, and redirect to a php page, called go.php
This php page would then take the variable and then redirect via header().

go.php
<?
if(isset($_GET['itemID'])){
header("Location:http://www.othersite.com/".$_GET['itemID']."?refid=store");exit();
}
?>

Seems like another option is to use the default PHP page and handle redirect on itemID condition. I'm assuming this is index.php?itemID=65165654654, in that case you could add 'go.php' snippet to that page, and scrap the rewrite handling all together. I might be misunderstanding.. so correct me if I'm wrong.
