How do I pass Variables from my site to another site without leaving my site?
<p>I would like to be able to send variables to another website without actually going to the website using php.</p>

<p>I am building an ecommerce website where the shipping warehouse is being outsourced. After the person checks out with their products, I would like to send some variables over to the shipper's website using $_GET['vars']. This is a completely different URL. The problem is, I don't want the person actually going to the shipper's webpage. I just want to ping that info over there.</p>

<p>Is is possible to send Variables via URL to another site without leaving yours?</p>
