fake referrer in cURL

[etrader]

When making a fake identity in cURL, we use

curl_setopt($ch, CURLOPT_USERAGENT, 'Googlebot/2.1 (http://www.googlebot.com/bot.html)'); 

but which is better for the referrer:

curl_setopt($ch, CURLOPT_AUTOREFERER, true); 

or

curl_setopt ($ch, CURLOPT_REFERER, "http://www.google.com/bot.html");

well the first one makes it automatic, so it will be whatever it really is.  The 2nd one you get to explicitly state what it is.  Seeing as how you are trying to fake stuff, you should go for the 2nd (CURLOPT_REFERER)

Thanks for your informative reply. One more question. Does the order has an influence on cURL processing? I mean changing the order of lines in

curl_setopt($ch, CURLOPT_USERAGENT, 'Googlebot/2.1 (http://www.googlebot.com/bot.html)');
curl_setopt($ch, CURLOPT_URL,"http://www.site.com");
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_REFERER, 'http://www.google.com/bot.html'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);

There is one note in the manual that mentions rearranging order of calls to curl_setopt() for posting data, but other than that, afaik it doesn't matter which order you put that stuff in.
