CURLMBS through a proxy script

Hi, I have a Xojo web application that uses CURLMBS for URL requests that need proxy settings:
d.OptionProxy = proxyAddress
d.OptionProxyPort = proxyPort.ToInteger
d.OptionProxyType = d.kPROXY_HTTP

This works fine. But the client has another server where they set up a “proxy script” rather than a proxy server, for which they just provided a URL but I cannot figure out how to move from a proxy server setup tp a call using a proxy script.

Does anyone have information to share on such?


Mystery solved! The script returns the proxy server address and port to use for CURLMBS!!!
