How to snatch the cookie content from the server response? Should I use a text array and read it line by line, some IndexOf / LastIndexOf combination or RegEx? Also if I go line by line, is it better to send a dedicated HEAD request instead of having to split hundreds of lines of the source html.

I am really new to this server client communication and don't want to use lame logic due to ignorance

PHP:

$endhead = strpos($content,"\r\n\r\n");
            $EL = "\r\n";
            if($endhead===FALSE){
                $endhead = strpos($content,"\n\n");$EL = "\n\n";
            }
            if($endhead===FALSE){
                $endhead = strpos($content,"\n\l\n\l");$EL = "\n\l";
            }
                $head = substr($content,0,$endhead);
                $headers = explode($EL,$head);
                foreach($headers as $HEAD){
                    list ($key, $value) = split(':', $HEAD, 2);
                    if (trim($key) == 'Set-Cookie') {
                        $value = trim($value);
                        $p1 = strpos($value, '=');
                        $p2 = strpos($value, ';');
                        $key = substr($value, 0, $p1);
                        $val = substr($value, $p1 +1, $p2 - $p1 -1);
                        $ret['cookies'][$key] = $val;
                    } else {
                        $ret['headers'][trim($key)] = trim($value);
                    }
                }

therefore $ret['cookies']['PHPSESSID'] would be fre54h546hgfngr5v2pg5d5dgh9gf

whoops you posted in C# section... that's php.. still works.

Yeah well I just need the best way. The kind of language doesn't really matter for me as it's just different syntax.
Here's how I'm doing it right now:

Code:

int StartCookie = (pageHTML.IndexOf("Set-Cookie: ") + 12);
int EndCookie = pageHTML.IndexOf(";", StartCookie);
int CookieLength = (EndCookie - StartCookie);
string CookieString = pageHTML.Substring(StartCookie, CookieLength);

Getting the cookie name & value, best practice?
