CURL - how to get URL of returned page?

Is there a way to get the URL of the page that is returned when using Curl? If I look at CURLINFO_EFFECTIVE_URL value from the return of curlget_info(), all I see is the URL I requested, not the one that is returned. I am trying to write an URL checking script against a site that may return a page other than the one you requested without it being seen as a 302 redirect status. Even though my situation is somewhat out of the norm, I would imagine there are cases where people would want to see the URL with a 302 status. Am I missing something? Does anyone have any suggestions for me? Thanks, Marianne
