Transparent Proxy

[KSchex]

Hi all, I am having a problem with the Transparent Proxy.  I have reliably been running my own UI on a NAS with Apache (based on HAD using the REST commands).  Since the NAS is primarily for backup, I set up XAMPP on a WIN 10 machine and copied my files and directory structure over.  PHP and CURL are enabled (and tested) in Apache as well as .htaccess.  I can call my UI but I have no data.  I get the following error:

--------------- 

Error accessing /rest/nodes/ZW004_1: Error: Invalid XML:

Warning: Use of undefined constant REQUEST_URI - assumed 'REQUEST_URI' (this will throw an Error in a future version of PHP) in C:\xampp\htdocs\rest\isyProxy.php on line 35

 

Notice: Undefined variable: header in C:\xampp\htdocs\rest\isyProxy.php on line 22

Line 22     curl_setopt ($curl, CURLOPT_HEADER, (int)$header);

Line 35      $reply = curl("http://$isyIp/" . ltrim($_SERVER[REQUEST_URI],"/"), $isyUser, $isyPassword);

 

I don’t have a real good understanding of curl or operation of the proxy.  Any pointers or assistance would be really appreciated.  Thanks in advance..
