Get location when redirected

Hello,

First, a *huge* thank you for this powerful class. I'm using it a lot in my web spiders, parsers, robots...

Second, I was using the good $follow_redirect feature but I was disappointed: I couldn't retrieve the URL of the page where I was finally redirected at the end.
This small suggestion adds an extra server header, to know where we go...

---[ OPEN ]--- // the main class

http.php


---[ FIND ]--- // approx. line 1318

if(strlen($error=$this->Close())==0
&& strlen($error=$this->Open($arguments))==0
&& strlen($error=$this->SendRequest($arguments))==0)
{
$this->redirection_level++;
if($this->redirection_level>$this->redirection_limit)
$error="it was exceeded the limit of request redirections";
else
$error=$this->ReadReplyHeaders($headers);
$this->redirection_level--;
}
if(strlen($error))
return($this->SetError($error));

---[ ADD AFTER ]--- // approx. line 1331

$headers['http_lib__redirected_to'] = $location;


--[ SAVE AND CLOSE ]---



Obviously, the header key must be recognizable enough because you don't want to parse it as a *server* header ;)

Anyway, this was just to tell you about the idea I got (because I needed it, of course ^^).
Another interesting thing could be to add a kind of "URL route" to know where the request has passed before arriving.

Once again, well done with this class!
Best regards,

You can retrieve the final URL using some of the class variables like this:

$http->protocol.'://'.$http->host_name.':'.($http->host_port ? $http->host_port : '').$http->request_uri

Hmmm... you're right!
Better way to do that indeed :)

Thank you!
