when I have cUrl seet up with CURLOPT_FOLLOWLOCATION =>FALSE,
I am getting a 302, moved temporarily.
How do I find out the URL it is being redirected to ?
The effectiveURL that is returned is the one I sent the request to.

Thanks, is there a way to obtain the Location response header
from cURL ?

Maybe - but since it is also neccessary to check the header size to
separate the header from the body I refered to the example. And finally
you got the right hint - didn't you? ;-)

Actually, suggesting that you RTFM yourself would have been most clear.
I understand not knowing about Location and HTTP spec, and not knowing
where to look for that. You should learn how to find things in
libraries that you're using though.

I don't know if I got it or not. Perhaps you could be a bit more
clear ?

Actually, I not only read the manual, I studied it (and the
coments) and still missed curlopt_header.... (as usual) until I
had sent my first message.
Sometimes when you are new to an area it is hard to
find/understand the fine print.

using:
function curl_getNoFollow($url, array $get = NULL, array $options
= array() ){
$defaults = array(
CURLOPT_HEADER => 0,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_FORBID_REUSE => 1,
CURLOPT_TIMEOUT => 30,
CURLOPT_SSL_VERIFYPEER =>0,
CURLOPT_COOKIEFILE => '/tmp/cookies.txt',
CURLOPT_COOKIEJAR=> '/tmp/cookies.txt',
CURLOPT_HEADER =>TRUE,
CURLINFO_HEADER_OUT => TRUE,
CURLOPT_FOLLOWLOCATION =>FALSE,
CURLOPT_USERAGENT =>'Mosilla/5.0(Windows NT 6.1,;WOW64,rv21.0)
Gecko/20100101 Firefox/21.0)',
);
$ch = curl_init();
curl_setopt ($ch,CURLOPT_URL, $url);
curl_setopt_array($ch, ($options + $defaults));
$result = curl_exec($ch);
$eurl = curl_getinfo($ch,CURLINFO_EFFECTIVE_URL);
$http =curl_getinfo($ch,CURLINFO_HTTP_CODE);
$resultx =array($result, $eurl, $http,); // result is an
array($result, $eurl, $http)
curl_close($ch);
return $resultx;
}
I get:
url: http://www.mydomain.com/login/login.cfm, http: 302
note the lack of information about the refer to address, which I
need so I can follow.

A quick & dirty example without any error handling etc. - just to get
the idea:
<?php
$options = array(
CURLOPT_URL => 'http://mydomain.example/foobar',
CURLOPT_HEADER => true,
CURLOPT_FOLLOWLOCATION => false,
CURLOPT_RETURNTRANSFER => true
);
$ch = curl_init();
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
$resultcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
if($resultcode == 302)
$redirect = curl_getinfo($ch, CURLINFO_REDIRECT_URL);
else
$redirect = '';
echo 'Effective URL: '.$url.'<br/>';
echo 'HTTP result code: '.$resultcode.'<br/>';
echo 'Redirection: '.$redirect.'<br/>';
curl_close($ch);
?>
See in action at <http://arnowelzel.de/samples/curl-sample.php>
CURLINFO_REDIRECT_URL is not in the documentation but it was added in
PHP 5.3.7. Also see <http://php.net/ChangeLog-5.php>.
If this does not work for you (e.g. because you have an older PHP
version), you have to extract the location header "manually".

I like to think of the premise that if you don't know what you don't
know, you don't know what there is to know.

that helps. The php I have available is 5.3, so hints at
extracting it "manually?"

In the example above you will get the headers in $result.
With curl_getinfo(CURLINFO_HEADER_SIZE) you can also check how long the
header part in $result is (beginning with the first character), so
$headers = substr($result, curl_getinfo(CURLINFO_HEADER_SIZE));
should give you all headers.
HTTP headers are in the form
Header1: Value
Header2: Value
[...]
And the redirection URL is
Location: URL
So try to find the "Location: " part and use the remaining text up to
the line break.
BTW: Using tools like the Firebug AddOn for Firefox help a lot to
understand HTTP headers.

Thanks much. Yes I do use Firebug and it is helpful. Just can't
use it with cURL.
I am going to try to upgrade to php5 version 5.4 later today.
Again, thanks for the help.
