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
