Getting a users IP when cURL'd?
<p>On some of my sites I have cURL pulling a script from another one of my domains - that script needs to get access to the IP of the person visiting the site, but I'm stumped at how to do that.</p>

<p>Because I'm using cURL, the REMOTE_ADDR variable is the server's IP address.</p>

<p>How can I collect the user's IP address?</p>
