Multi_Curl using authentication

[7331]

I am trying to login to a site and then call numerous URLs to get the source and scrape for images. It works fine using regular curl but when I try to use multi_curl I am getting back the exact same response. So that I only have to login once I am resuing the curl resource (this works fine with regular curl) and I think this may be the reason why it is returning the same response.Does anyone know how to use multi_curl but authenticate first?Here is the code I am using:\[code\]<?php // LICENSE: PUBLIC DOMAIN // The author disclaims copyright to this source code. // AUTHOR: Shailesh N.
