I'm not sure if all 'major' hosting companies (there are some obscure 
companies used by big organisations and governmental bodies) provide curl.

Maybe the best implementation is to use a handler. After the cURL 
handler we can always add a plain PHP version or one that uses another 
library.

Without cURL it would be quite easy: do a GET and stop retrieving 
information after the headers arrived.
