The curl_getinfo function returns a large amount of metadata about the result of the HTTP request. However, for some reason it doesn't contain the information I currently want, which is the target URL if the request returns an HTTP redirect code.

I did not use CURLOPT_FOLLOWLOCATION because I wanted to handle specific redirect codes as special cases.

If cURL can track redirects, why can't it tell me what they redirect to when it doesn't?

Of course, I can set the CURLOPT_HEADER flag and select the Location header. But is there a more efficient way?
