PHP cURL: modify/overwrite Connection header
With PHP cURL library I have ability to operate with HTTP headers, but how about Connection header? When I'm sending any request, cURL always appends it with Connection: Keep-Alive and when I'm trying to modify this header to this one Connection: keep-alive (lowercase 'keep-alive'), it append instead, two lines as result:
Connection: Keep-Alive
Connection: keep-alive
How can I change it instead of append? Thanks.
UPDATE: I'm doing it in this way:
$url = 'http://some.host/path';
$ch = curl_init();
$hdrs = array( 'Host: some.host',
'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0',
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: en-US;q=0.5,en;q=0.3',
'Accept-Encoding: gzip, deflate',
'Connection: keep-alive');
curl_setopt($ch, CURLOPT_HTTPHEADER, $hdrs);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_VERBOSE, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$data = curl_exec($ch);
UPDATE 1: Only solution I found (probably not the best) is to edit php_curl library file with hex editor.
